Issue - while storing results in cache we store the event map which
contains aggregator names mapped to values. Now when someone fire same
query after renaming aggs, the cache key will be same but the event
will contain metric values mapped to older names which leads to wrong
results.
Fix - modify cache to not store raw event but the actual list of values
only.

* Fix resource leak in `io.druid.segment.IndexIO.DefaultIndexIOHandler#validateTwoSegments(java.io.File, java.io.File)`
* Un-deprecate `close()` in `QueryableIndex` and make it inherit `Closeable`
* Fix resource leaks in various unit tests
* Add `CloserRule` for closing out resources

* 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
