libceph: add lingering request and watch/notify event framework
Lingering requests are requests that are sent to the OSD normally but tracked also after we get a successful request. This keeps the OSD connection open and resends the original request if the object moves to another OSD. The OSD can then send notification messages back to us if another client initiates a notify. This framework will be used by RBD so that the client gets notification when a snapshot is created by another node or tool.
