If GROUP BY clause has distribution column as one of the grouping items, let FQS
ship the query even if it has aggregates. Similarly, if there is distribution
column in the DISTINCT clause, let FQS ship the DISTINCT clause. The presence of
the distribution column ensures that the results will be evaluated on the
datanodes completely in both the cases.
