* 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.
* Add `invokeForeignLoader` to commonize the way tasks are attempted to be launched in a foreign class loader
* Add `buildClassLoader` to accomplish the common tasks for hadoop jobs when building a ClassLoader
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
* Remove hard-coded azure path manipulation from the puller.
* Fix segment size not being zero after uploading it do Azure.
* Remove both index and desc files only on a success upload to Azure.
* Add Azure container name to load spec.
This patch would help future-proof azure deep-storage module and avoid
having to introduce ugly backwards-compatibility fixes when we want to
support multiple containers or moving data between containers.
