Summary
-------
This is on top of HBASE-4506 but doesn't require it.
commit 17d3b8856a8e7c803463fb37b1bd4691d0a02ba9

HBASE-4509 [hbck] Improve region map output
Details:
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.
This patch:
* improves output by using Bytes.toStringBinary (which escapes binary) instead of Bytes.toString when printing keys,
* suggests some repair actions, and
* collects "overlap group" that groups regions that are overlapping.
This addresses bug HBASE-4509.
