Create replication destination/source based on annotations

[cooktheryan]

I'd like to be able to supply an annotation on PVCs and have a replication destination or replication source to be magically defined.

A new controller would be created. An idea would be to create the controller and also define some generic values that could be overwritten

Given the configuration required (addresses, credentials), I don't think this can reasonably be handled in an annotation/label on the PVC. It would require the equivalent of a "ReplicationClass" object to handle the configuration, much like a StorageClass.
