Laszlo Gaal 9af59bfe2b IMPALA-4153: Fix count(*) on all blank('') columns - test

This change adds test coverage for the fixes committed for
IMPALA-2399 in commit 9ed3b685a1.
It uses the table nulltable in the workload functional-query
to verify the materialization and counting of NULL and empty-
valued columns. The test can be run on any supported storage
and compression combination.

This directory contains Impala test workloads. The directory layout for the workloads should follow:

workloads/
   <data set name>/<data set name>_dimensions.csv  <- The test dimension file
   <data set name>/<data set name>_core.csv  <- A test vector file
   <data set name>/<data set name>_pairwise.csv
   <data set name>/<data set name>_exhaustive.csv
   <data set name>/queries/<query test>.test <- The queries for this workload
