Log:
HBase FSCK: Ignore Non-numeric Directories

Summary:
Ran HBCK on prod cluster & it threw an error for .META./compaction.dir.  Layout 
in
HBase is: /hbase/table/region & region is always a numeric hash.  So, we should
ignore directories at the region level that are non-numeric.

Test Plan:
bin/hbase fsck
