Review request for drill, Jacques Nadeau, Mehant Baid, Parth Chandra, and Venki Korukanti.


Changes
-------

Adding venki


Bugs: DRILL-2173
    https://issues.apache.org/jira/browse/DRILL-2173


Repository: drill-git


Description (updated)
-------

Adds a new interface for UDFs to access partition information. Together with 2060 which allows
constant expression folding this will allow UDFs that can query against partition information
and then scan a subset of data. Example use case, find the most recent directory and only
that partition worth of data.

Testing (updated)
-------

Test have been run on a very recent version, made a few minor cleanup edits since, waiting
on another run, but do not anticipate issues.


Thanks,
