dbwrap_ctdb: Instrument chainunlock timing
We need an indication whether we run into the fcntl thundering
herd. fcntl unlock should be blindingly fast in the normal case. If it
takes longer than 5 milliseconds, warn. The timeout can be adapted by
setting
ctdb:unlock_warn_threshold = <number-of-milliseconds>
