> Whenever a Scanner lease expires, the RegionServer will close it automatically and log a message to complain.  I would like the RegionServer to increment a counter whenever this happens and expose this counter through the metrics system, so we can plug this into our monitoring system (OpenTSDB) and keep track of how frequently this happens.  It's not supposed to happen frequently so it's good to keep an eye on it.
