Delete Snapshots

Once a Snapshot is no longer needed, it can be safely deleted from a Workload.
The retention policy will automatically delete the oldest Snapshots according to the configure policy.
You have to delete all Snapshots to be able to delete a Workload.
Deleting a TrilioVault Snapshot will not delete any Openstack Cinder Snapshots. Those need to be deleted separately if desired.
