Get replica volume ref for DR
In DR scenario, there are two sites with two independent OpenStack, one is production site, one is DR site. Users use replication for volumes
in production site and the storage backend will make the replication between two sites.
When disaster happens, cloud admin or DR manage system which is over the OpenStack want to failover those volumes which are in DR site now by using manage volume API, but
they can't get the replica volume ref even driver has recorded the ref info into Cinder database.
This function will be helpful in DR scenario for production & disaster recovery sites which are two independent OpenStack cloud. Cloud admin and DR manage
system cloud get the replica volume ref after creating replicating volumes in production site, and then manage replicated volumes in DR site for failover
when disaster happens.
