ceph: reset osd after relevant messages timed out
This simplifies the process of timing out messages. We keep lru of current messages that are in flight. If a timeout has passed, we reset the osd connection, so that messages will be retransmitted. This is a failsafe in case we hit some sort of problem sending out message to the OSD. Normally, we'll get notification via an updated osdmap if there are problems. If a request is older than the keepalive timeout, send a keepalive to ensure we detect any breaks in the TCP connection.
