> Adds a small chore to master.ServerManager that logs the number of reporting region servers, the number of region servers declared dead (and their identity), and the average load. Uses the metaScanner period. Useful for those that tail the master log to get a sense of system health, or are considering writing Nagios monitors etc. which do the same.
