Code Issues Proposed changes

NetApp cDOT: Fix model update for cheesecake volumes 

Host level replication capability was added to the NetApp
cDOT Block and File drivers through
I87b92e76d0d5022e9be610b9e237b89417309c05.
However, volumes created on these backends did not
have the 'replication_status' field set.

Fix this by returning model updates to the volume manager.
