osd_client, rbd: add support for version 2 of watch/notify Support watch/notify 2 in osd_client and update rbd for compatibility. Map ceph_osd_event to expected watch/notify messages and store watch and watch error callbacks. Implement CEPH_OSD_WATCH_OP_PING and CEPH_OSD_WATCH_OP_RECONNECT. Handle CEPH_WATCH_EVENT_DISCONNECT. Handle CEPH_WATCH_EVENT_NOTIFY_COMPLETE and provide a data item for clients to consume. v2: incorporated changes from Mike, Josh, and Ilya. Changed notify-ack data to page vector and size instead of ceph_msg_data and other fixes.
