      Makes it so the recently added HBCKServerCrashProcedure -- the SCP that gets invoked when an operator schedules an SCP via hbck2 scheduleRecoveries command -- now works the same as SCP EXCEPT if master knows nothing of the scheduled servername. In this latter case, HBCKSCP will do a full scan of hbase:meta looking for instances of the passed servername. If any found it will attempt cleanup of hbase:meta references by reassigning any found OPEN or OPENING and by closing any in CLOSING state.

      Used to fix instances of what the 'HBCK Report' page shows as 'Unknown Servers'.
