bq.      HBASE-4509 [hbck] Improve region map output
bq.  
bq.  Details:
bq.  
bq.  HBASE-4375 added a region coverage visualization to hbck in details mode. When users
have binary row keys the output is difficult to parse (awk/sed) or pull into programs (numeric,
excel) capable of handling tsv formatted data.
bq.  
bq.  This patch:
bq.  
bq.  * improves output by using Bytes.toStringBinary (which escapes binary) instead of Bytes.toString
when printing keys,
bq.  * suggests some repair actions, and
bq.  * collects "overlap group" that groups regions that are overlapping.
bq.  
bq.  
bq.  This addresses bug HBASE-4509.
