DRILL-3496: Updates from review comments
DRILL-3496: Update: Multiple log msgs. -> single, aligned multi-line message.
Main: Changed avoidance of original single hard-to-read list from
first draft's multiple single-item log calls (resulting in multiple log
calls/entries) to single log call with aligned multi-line message.
Also revised message wording, etc.
DRILL-3496: Update 2: Some DEBUG -> INFO; another single multi-line msg.
- logger.debug(...) -> logger.info(...) for config. file messages
- changed drill-module.conf to single multi-line message like
scanForImplementations cases
DRILL-3496: Update 3: Various review comment responses.
- Removed isTraceEnabled/etc. guards.
- Simplified logging line break/indentation code.
- Added some more "final".
- Undid logger cleanup. :-(
