remove backwards compatible code

1) remove backwards compatible and deprecated code
2) make hashed partitions spec default
more cleanup
more cleanup
minor edits based on Vad's feedback
added missing anchor to fix broken internal link
added link to DimensionSpec for alternative way to provide dimensions
expanded and clarified OrderByColumnSpec section
Update logging to https://github.com/druid-io/druid-api/pull/27
Fix query by segment
* Changed topN queries to use joda Interval instead of string values
* topN by segment now implements BySegmentResultValue<Result<TopNResultValue>> instead of BySegmentResultValue<TopNResultValue>
* Added a unit test which failed uner the prior implementation.
Merge remote-tracking branch 'origin/master' into druid-845
Fix a couple of bugs with retry query runner after testing it locally
add test
change default settings for retry
Add benchmarking for bitmaps

Here are the results on my laptop:
