As noted in lp#1691570, there is an issue with storage I/O during
coro-thread cleanup that affects the swift-object-replicator's ability
to complete replication successfully. This is most easily witnessed by
the lack of the every 5 minute replicated percentage complete messages
that should come from the swift-object-replicator daemon to syslog.
This patch monitors for and alerts on the condition of the "replicated"
line missing from syslog within the past 15 minutes.
