share with snapshot can be unmanaged

[Valeriy Ponomaryov]

Shares with snapshots should not be able to be deleted or unmanaged.

But Manila does not make verification for presence of snapshots for share that is requested to be managed.

I am not sure if this is a bug or not. I need to confirm what GlusterFS and Ceph do. At most, this probably should be something that the driver should be able to deal with in case that the backend system does support the ability to delete a share that contains snapshots.
