    [SPARK-6466][SQL] Remove unnecessary attributes when resolving GroupingSets

    When resolving `GroupingSets`, we currently list all outputs of `GroupingSets`'s child
plan. However, the columns that are not in groupBy expressions and not used by aggregation
expressions are unnecessary and can be removed.
