[hbck] Improve region map output

                 Key: HBASE-4509
                 URL: https://issues.apache.org/jira/browse/HBASE-4509
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.92.0, 0.94.0, 0.90.5
            Reporter: Jonathan Hsieh

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 "problem group" that groups regions that are overlapping.
