refactor(kubernetes): Convert all V2 code in clouddriver-kubernetes t…

…o Java (#3947)

* fix(appengine): Fix package name of MutableCacheData

At some point the MutableCacheData class was moved to the appengine
provider, but the package name still references kubernetes. Update
the package name in the class, and all of the references.

* refactor(kubernetes): Move shared logic out of V1 provider

KubernetesAtomicOperationConverterHelper is used by both the V1 and V2
providers, so should not live in the V1 directory tree; move it up to
the base level.

KubernetesApiClientConfig is only used by the V1 provider, so it should
be moved into the v1 directory tree.

* refactor(kubernetes): Convert ConfigurationProperties to Java

Also, move the top-level classes in that file to their own files
as part of the Java conversion.

In order to make this work better with Lombok-generated accessors,
change calls to the accessors: booleans should use isXXX instead of
getXXX, and change the capialization of getoAuthScopes.

* refactor(kubernetes): Convert a few more classes to Java

Also, as part of this conversion update
KubernetesAtomicOperationConverterHelper to use generics, which
avoids a lot of necessary casting and provides extra type safety.
This extra type safety surfaced a bug in the resize server group
converter where we were incorrectly converting the description to a
deploy manifest description which compiled before but no longer does.

* refactor(kubernetes): Convert KubernetesCloudProvider to Java

Also standardize static access to the ID to just use the public
static final field instead of mixing use of the field and the
auto-generated static accessor.

* refactor(kubernetes): Convert configuration to Java

This is the last non-test class in clouddriver-kubernetes that is
still in groovy (excluding classes used exclusively by the V1 provider).

* refactor(kubernetes): Remove unused Getter annotation
