etag property
etag is used for optimistic concurrency control as a way to help prevent
simultaneous updates of a RestoreChannel from overwriting each other.
It is strongly suggested that systems make use of the 'etag' in the
read-modify-write cycle to perform RestoreChannel updates in order to
avoid race conditions: An etag is returned in the response to
GetRestoreChannel, and systems are expected to put that etag in the
request to UpdateRestoreChannel or DeleteRestoreChannel to ensure that
their change will be applied to the same version of the resource.
Output only.
