stack updated HBASE-22723:
--------------------------
Release Note:
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.

> 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.
