Share replica create API does not allow to specify share network and
forces to use parent share's share network. This is problem for some
use-cases, e.g. migration from one share network to another share
network via replication is not possible. Fixed by allowing to pass
'share-network' option for share replica create API and make sure both
parent share-network and user provided share-network will have same
security service association.
