yogesh 53364e07a3 Handle manage/unmanage for replicated shares
Managing a share with a share type that has replication_type
extra_spec must be allowed. Drivers are expected to fail
this operation if the share was part of a replication relationship
that Manila does not know about.

Unmanaging a share with replicas must not be permitted
until all replicas are removed.

Managing and unmanaging of snapshots must not
be permitted for a share that has replicas.

Modify the NetApp driver for manage_existing to check
for existing replicas.

Also fix issue with manage retry where the share
data was being altered inappropriately by a DB API.
