* Inverted function arguments to compose postProcFn for GroupBy queries
with havingspec + limitspec.
* Replaced query.getLimitSpec() with null in GroupByQueryToolChest's
mergeGroupByResults
* Added unittest to verify functionality
that is if complex agg did not implement inputSizeFn() so
that segment metadata query shows atleast some information.
also instead of COMPLEX, return type of data stored.
renamed all [Max/Min]*.java to [DoubleMax/DoubleMin]*.java and created [Max/Min]AggregatorFactory.java which can be removed when we dont need the min/max aggregator type backward compatibility

fixes#1330,
Avoid creating Period instance as creating a Period from Long.MAX_VALUE
throws arithmetic exception.
After this query metric will emit duration in seconds instead of
minutes.
* Add some unit tests
* Add io.druid.segment.IndexMerger.reprocess for quick re-indexing of data
* Add dim-value validation to validation checker (instead of ONLY index #)
* General code refactoring to make things a little easier to read
on postAggregations which are removed in the forwarded query.
Add a unit test to replicate the issue.
Add a query that can replicate this issue into integration test.
- compression for single-value dimensions using CompressedVSizeIntsIndexedSupplier
- makes dimension compression configurable via IndexSpec
- IndexSpec also enables configuring bitmap and metric compression
