mgr/dashboard: Add support for managing RBD mirroring
The current Ceph manager dashboard provides a "read-only" insight into a configured RBD mirroring setup. This feature should be expanded to support the administrator in setting up mirroring, e.g. by enabling/disabling the mirroring on a pool, adding/removing the peer cluster, enabling the journaling feature on RBD images. This assumes that the rbd-mirror Daemon is already up und running.

Capturing a hopefully useful comment from Jason Dillaman about the configuration:
The rbd-mirror daemons are essentially stateless. The only piece of data they need is the monitor addresses, CephX user id, and associated keyring. All other details they can pull from the cluster (including the remote cluster monitor addresses/CephX ids/keyrings). These details are configured on a per pool basis.
