Remove auto creation of container for azure repository

Follow up of #22857 where we deprecate automatic creation of azure containers.

BTW I found that the `AzureSnapshotRestoreServiceIntegTests` does not bring any value because it runs basically a Snapshot/Restore operation on local files which we already test in core.

So instead of trying to fix it to make it pass with this PR, I simply removed it.
