// Apply submit an operation to apply a snapshot to current subscription. For each snapshot, only subscriptions
// included in the applyScope of Snapshot - Take can apply it.<br />
// The snapshot interfaces are for users to backup and restore their face data from one face subscription to another,
// inside same region or across regions. The workflow contains two phases, user first calls Snapshot - Take to create a
// copy of the source object and store it as a snapshot, then calls Snapshot - Apply to paste the snapshot to target
// subscription. The snapshots are stored in a centralized location (per Azure instance), so that they can be applied
// cross accounts and regions.<br />
// Applying snapshot is an asynchronous operation. An operation id can be obtained from the "Operation-Location" field
// in response header, to be used in OperationStatus - Get for tracking the progress of applying the snapshot. The
// target object id will be included in the "resourceLocation" field in OperationStatus - Get response when the
// operation status is "succeeded".<br />
// Snapshot applying time depends on the number of person and face entries in the snapshot object. It could be in
// seconds, or up to 1 hour for 1,000,000 persons with multiple faces.<br />
// Snapshots will be automatically expired and cleaned in 48 hours after it is created by Snapshot - Take. So the
// target subscription is required to apply the snapshot in 48 hours since its creation.<br />
// Applying a snapshot will not block any other operations against the target object, however it is not recommended
// because the correctness cannot be guaranteed during snapshot applying. After snapshot applying is completed, all
// operations towards the target object can work as normal. Snapshot also includes the training results of the source
// object, which means target subscription the snapshot applied to does not need re-train the target object before
// calling Identify/FindSimilar.<br />
// One snapshot can be applied multiple times in parallel, while currently only CreateNew apply mode is supported,
// which means the apply operation will fail if target subscription already contains an object of same type and using
// the same objectId. Users can specify the "objectId" in request body to avoid such conflicts.<br />
// * Free-tier subscription quota: 100 apply operations per month.
// * S0-tier subscription quota: 100 apply operations per day.
// Parameters:
// snapshotID - id referencing a particular snapshot.
