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.
