      When CatalogJanitor runs, it now checks for holes, overlaps, empty info:regioninfo columns and bad servers. Dumps findings into log. Follow-up adds report to new 'HBCK Report' linked off the Master UI.

      NOTE: All features but the badserver check made it into branch-2.1 and branch-2.0 backports.

    Description

      CatalogJanitor scans hbase:meta on a configurable period. Currently it just looks for splits and merges to gc. Might as well generate a report on stuff like holds, overlaps, empty regioninfos, and unknown servers while it is at it.
