Minor Description
By default, `TPCDSQueryBenchmark` runs all the TPC-DS queries.
So, it might help to add a new option to filter the queries that you want to run, e.g.,
to run q2, q4, and q6 only:
spark-submit --class <this class> --conf spark.sql.tpcds.queryFilter="q2,q4,q6"
--jars <spark sql test jar>
