Description of problem: Manila with CephFS and CephFS with NFS back ends allow creation of snapshots if the configuration option ``cephfs_enable_snapshots`` is set to True in the manila.conf file. However, it does not currently support the capability of creating a new share from a snapshot with these back ends. This is a feature gap relative to other manila back ends that support snapshots. Also, the Container Storage Interface (CSI) for container orchestrators like Kubernetes is adding snapshot support where it is assumed that snapshot capability implies the capability to create new "volumes" from snapshots. Since a manila CSI plugin is in progress we should have manila support for share creation from snapshots to meet expectations there as well.

The procedure for how to create a share from snapshot (storage backend agnostic) is already available here: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.2/html/storage_guide/assembly_shared-file-systems-service_osp-storage-guide#proc_creating-a-share-from-snapshot_configuring-manila.
