// Create create or rename a file or directory.    By default, the destination is overwritten and if the destination
// already exists and has a lease the lease is broken.  This operation supports conditional HTTP requests.  For more
// information, see [Specifying Conditional Headers for Blob Service
// Operations](https://docs.microsoft.com/en-us/rest/api/storageservices/specifying-conditional-headers-for-blob-service-operations).
// To fail if the destination already exists, use a conditional request with If-None-Match: "*".
// Parameters:
// filesystem - the filesystem identifier.
// pathParameter - the file or directory path.
// resource - required only for Create File and Create Directory. The value must be "file" or "directory".
// continuation - optional.  When renaming a directory, the number of paths that are renamed with each
// invocation is limited.  If the number of paths to be renamed exceeds this limit, a continuation token is
// returned in this response header.  When a continuation token is returned in the response, it must be
// specified in a subsequent invocation of the rename operation to continue renaming the directory.
// mode - optional. Valid only when namespace is enabled. This parameter determines the behavior of the rename
// operation. The value must be "legacy" or "posix", and the default value will be "posix".
// cacheControl - optional.  The service stores this value and includes it in the "Cache-Control" response
// header for "Read File" operations for "Read File" operations.
// contentEncoding - optional.  Specifies which content encodings have been applied to the file. This value is
// returned to the client when the "Read File" operation is performed.
// contentLanguage - optional.  Specifies the natural language used by the intended audience for the file.
// contentDisposition - optional.  The service stores this value and includes it in the "Content-Disposition"
// response header for "Read File" operations.
// xMsCacheControl - optional.  The service stores this value and includes it in the "Cache-Control" response
// header for "Read File" operations.
// xMsContentType - optional.  The service stores this value and includes it in the "Content-Type" response
// header for "Read File" operations.
// xMsContentEncoding - optional.  The service stores this value and includes it in the "Content-Encoding"
// response header for "Read File" operations.
// xMsContentLanguage - optional.  The service stores this value and includes it in the "Content-Language"
// response header for "Read File" operations.
// xMsContentDisposition - optional.  The service stores this value and includes it in the
// "Content-Disposition" response header for "Read File" operations.
// xMsRenameSource - an optional file or directory to be renamed.  The value must have the following format:
// "/{filesystem}/{path}".  If "x-ms-properties" is specified, the properties will overwrite the existing
// properties; otherwise, the existing properties will be preserved.
// xMsLeaseID - optional.  A lease ID for the path specified in the URI.  The path to be overwritten must have
// an active lease and the lease ID must match.
// xMsProposedLeaseID - optional for create operations.  Required when "x-ms-lease-action" is used.  A lease
// will be acquired using the proposed ID when the resource is created.
// xMsSourceLeaseID - optional for rename operations.  A lease ID for the source path.  The source path must
// have an active lease and the lease ID must match.
// xMsProperties - optional.  User-defined properties to be stored with the file or directory, in the format of
// a comma-separated list of name and value pairs "n1=v1, n2=v2, ...", where each value is base64 encoded.
// xMsPermissions - optional and only valid if Hierarchical Namespace is enabled for the account. Sets POSIX
// access permissions for the file owner, the file owning group, and others. Each class may be granted read,
// write, or execute permission.  The sticky bit is also supported.  Both symbolic (rwxrw-rw-) and 4-digit
// octal notation (e.g. 0766) are supported.
// ifMatch - optional.  An ETag value. Specify this header to perform the operation only if the resource's ETag
// matches the value specified. The ETag must be specified in quotes.
// ifNoneMatch - optional.  An ETag value or the special wildcard ("*") value. Specify this header to perform
// the operation only if the resource's ETag does not match the value specified. The ETag must be specified in
// quotes.
// ifModifiedSince - optional. A date and time value. Specify this header to perform the operation only if the
// resource has been modified since the specified date and time.
// ifUnmodifiedSince - optional. A date and time value. Specify this header to perform the operation only if
// the resource has not been modified since the specified date and time.
// xMsSourceIfMatch - optional.  An ETag value. Specify this header to perform the rename operation only if the
// source's ETag matches the value specified. The ETag must be specified in quotes.
// xMsSourceIfNoneMatch - optional.  An ETag value or the special wildcard ("*") value. Specify this header to
// perform the rename operation only if the source's ETag does not match the value specified. The ETag must be
// specified in quotes.
// xMsSourceIfModifiedSince - optional. A date and time value. Specify this header to perform the rename
// operation only if the source has been modified since the specified date and time.
// xMsSourceIfUnmodifiedSince - optional. A date and time value. Specify this header to perform the rename
// operation only if the source has not been modified since the specified date and time.
// xMsClientRequestID - a UUID recorded in the analytics logs for troubleshooting and correlation.
// timeout - an optional operation timeout value in seconds. The period begins when the request is received by
// the service. If the timeout value elapses before the operation completes, the operation fails.
// xMsDate - specifies the Coordinated Universal Time (UTC) for the request.  This is required when using
// shared key authorization.

// "x-ms-lease-id" to renew an existing lease. Use "release" and specify the "x-ms-lease-id" to release a
// lease.
// filesystem - the filesystem identifier.
// pathParameter - the file or directory path.
// xMsLeaseDuration - the lease duration is required to acquire a lease, and specifies the duration of the
// lease in seconds.  The lease duration must be between 15 and 60 seconds or -1 for infinite lease.
// xMsLeaseBreakPeriod - the lease break period duration is optional to break a lease, and  specifies the break
// period of the lease in seconds.  The lease break  duration must be between 0 and 60 seconds.
// xMsLeaseID - required when "x-ms-lease-action" is "renew", "change" or "release". For the renew and release
// actions, this must match the current lease ID.
// xMsProposedLeaseID - required when "x-ms-lease-action" is "acquire" or "change".  A lease will be acquired
// with this lease ID if the operation is successful.
// ifMatch - optional.  An ETag value. Specify this header to perform the operation only if the resource's ETag

// Update uploads data to be appended to a file, flushes (writes) previously uploaded data to a file, sets properties
// for a file or directory, or sets access control for a file or directory. Data can only be appended to a file. This
// operation supports conditional HTTP requests. For more information, see [Specifying Conditional Headers for Blob
// Service
// Operations](https://docs.microsoft.com/en-us/rest/api/storageservices/specifying-conditional-headers-for-blob-service-operations).
// Parameters:
// action - the action must be "append" to upload data to be appended to a file, "flush" to flush previously
// uploaded data to a file, "setProperties" to set the properties of a file or directory, or "setAccessControl"
// to set the owner, group, permissions, or access control list for a file or directory.  Note that
// Hierarchical Namespace must be enabled for the account in order to use access control.  Also note that the
// Access Control List (ACL) includes permissions for the owner, owning group, and others, so the
// x-ms-permissions and x-ms-acl request headers are mutually exclusive.
// filesystem - the filesystem identifier.
// pathParameter - the file or directory path.
// position - this parameter allows the caller to upload data in parallel and control the order in which it is
// appended to the file.  It is required when uploading data to be appended to the file and when flushing
// previously uploaded data to the file.  The value must be the position where the data is to be appended.
// Uploaded data is not immediately flushed, or written, to the file.  To flush, the previously uploaded data
// must be contiguous, the position parameter must be specified and equal to the length of the file after all
// data has been written, and there must not be a request entity body included with the request.
// retainUncommittedData - valid only for flush operations.  If "true", uncommitted data is retained after the
// flush operation completes; otherwise, the uncommitted data is deleted after the flush operation.  The
// default is false.  Data at offsets less than the specified position are written to the file when flush
// succeeds, but this optional parameter allows data after the flush position to be retained for a future flush
// operation.
// contentLength - required for "Append Data" and "Flush Data".  Must be 0 for "Flush Data".  Must be the
// length of the request content in bytes for "Append Data".
// xMsLeaseAction - optional.  The lease action can be "renew" to renew an existing lease or "release" to
// release a lease.
// xMsLeaseID - the lease ID must be specified if there is an active lease.
// xMsCacheControl - optional and only valid for flush and set properties operations.  The service stores this
// value and includes it in the "Cache-Control" response header for "Read File" operations.
// xMsContentType - optional and only valid for flush and set properties operations.  The service stores this
// value and includes it in the "Content-Type" response header for "Read File" operations.
// xMsContentDisposition - optional and only valid for flush and set properties operations.  The service stores
// this value and includes it in the "Content-Disposition" response header for "Read File" operations.
// xMsContentEncoding - optional and only valid for flush and set properties operations.  The service stores
// this value and includes it in the "Content-Encoding" response header for "Read File" operations.
// xMsContentLanguage - optional and only valid for flush and set properties operations.  The service stores
// this value and includes it in the "Content-Language" response header for "Read File" operations.
// xMsProperties - optional.  User-defined properties to be stored with the file or directory, in the format of
// a comma-separated list of name and value pairs "n1=v1, n2=v2, ...", where each value is base64 encoded.
// Valid only for the setProperties operation.  If the file or directory exists, any properties not included in
// the list will be removed.  All properties are removed if the header is omitted.  To merge new and existing
// properties, first get all existing properties and the current E-Tag, then make a conditional request with
// the E-Tag and include values for all properties.
// xMsOwner - optional and valid only for the setAccessControl operation. Sets the owner of the file or
// directory.
// xMsGroup - optional and valid only for the setAccessControl operation. Sets the owning group of the file or
// directory.
// xMsPermissions - optional and only valid if Hierarchical Namespace is enabled for the account. Sets POSIX
// access permissions for the file owner, the file owning group, and others. Each class may be granted read,
// write, or execute permission.  The sticky bit is also supported.  Both symbolic (rwxrw-rw-) and 4-digit
// octal notation (e.g. 0766) are supported. Invalid in conjunction with x-ms-acl.
// xMsACL - optional and valid only for the setAccessControl operation. Sets POSIX access control rights on
// files and directories. The value is a comma-separated list of access control entries that fully replaces the
// existing access control list (ACL).  Each access control entry (ACE) consists of a scope, a type, a user or
// group identifier, and permissions in the format "[scope:][type]:[id]:[permissions]". The scope must be
// "default" to indicate the ACE belongs to the default ACL for a directory; otherwise scope is implicit and
// the ACE belongs to the access ACL.  There are four ACE types: "user" grants rights to the owner or a named
// user, "group" grants rights to the owning group or a named group, "mask" restricts rights granted to named
// users and the members of groups, and "other" grants rights to all users not found in any of the other
// entries. The user or group identifier is omitted for entries of type "mask" and "other".  The user or group
// identifier is also omitted for the owner and owning group.  The permission field is a 3-character sequence
// where the first character is 'r' to grant read access, the second character is 'w' to grant write access,
// and the third character is 'x' to grant execute permission.  If access is not granted, the '-' character is
// used to denote that the permission is denied. For example, the following ACL grants read, write, and execute
// rights to the file owner and john.doe@contoso, the read right to the owning group, and nothing to everyone
// else: "user::rwx,user:john.doe@contoso:rwx,group::r--,other::---,mask=rwx". Invalid in conjunction with
// x-ms-permissions.
// ifMatch - optional for Flush Data and Set Properties, but invalid for Append Data.  An ETag value. Specify
// this header to perform the operation only if the resource's ETag matches the value specified. The ETag must
// be specified in quotes.
// ifNoneMatch - optional for Flush Data and Set Properties, but invalid for Append Data.  An ETag value or the
// special wildcard ("*") value. Specify this header to perform the operation only if the resource's ETag does
// not match the value specified. The ETag must be specified in quotes.
// ifModifiedSince - optional for Flush Data and Set Properties, but invalid for Append Data. A date and time
// value. Specify this header to perform the operation only if the resource has been modified since the
// specified date and time.
// ifUnmodifiedSince - optional for Flush Data and Set Properties, but invalid for Append Data. A date and time
// value. Specify this header to perform the operation only if the resource has not been modified since the
// specified date and time.
// requestBody - valid only for append operations.  The data to be uploaded and appended to the file.
// xMsClientRequestID - a UUID recorded in the analytics logs for troubleshooting and correlation.
// timeout - an optional operation timeout value in seconds. The period begins when the request is received by
// the service. If the timeout value elapses before the operation completes, the operation fails.
// xMsDate - specifies the Coordinated Universal Time (UTC) for the request.  This is required when using
// shared key authorization.
