Alex Behm 1497002013 Added SHOW TABLE/COLUMN STATS command. 
Fixed the following stats-related bugs:
- Per-partition row count was not distributed properly via CatalogService
- HBase column stats were not loaded and distributed properly

Enhancements to test framework:
- Allow regex specification of expected row or column values
- Fixed expected results of some tests because the test framework
  did not catch that they were incorrect
