Review request for drill and Jacques Nadeau.
Bugs: DRILL-2568
https://issues.apache.org/jira/browse/DRILL-2568
Repository: drill-git
Description
-------
Drop the filter plan node if all conjuncts in the filter have been pushed as
part of partition pruning, except for the situation where the new set of files
is empty - we add a single file in that case, so the Filter is preserved in
that case.
