As a monitoring user i need a new RBD mirror daemon performance counter and the associate metric in Ceph exporter in order to provide information about connection health (ceph layer) with the remote cluster. A performance counter must provide this information, Ceph exporter should conver the perf. counter to prometheus metric. Example: ceph_rbd_mirror_connection_health{ "instance_id":"2342", } = 0=OK, 1=NOT_CONNECTED, 2=FLAPPING, 3=ERROR
