rbd mirroring CLI calls are async and it doesn't wait for the operation to be completed. ex:- `rbd mirror image enable` it will enable the mirroring on the image but it doesn't ensure that the image is mirroring enabled and healthy primary. The same goes for the promote volume also. This commits adds a check-in PromoteVolume to make sure the image in a healthy state i.e `up+stopped`. note:- not considering any intermediate states to make sure the image is completely healthy before responding success to the RPC call.
