1. Revamped test output logging:
  a. Cleaned up debugging log information some of which is presented in debug mode.
  b. Formatted log output supposedly easier for searching and triage.
  c. Removed TestNG generated logs.
  d. Simplified log4j output to suppress timestamps and output classes and line numbers.
2. Fixed a bug - if a query executes successfully but returns no rows, test now fails with verification if baseline contains rows.
