Add support for `grouping` aggregate function in the SQL planner

[andygrove]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
I would like to be able to run queries with grouping sets (such as ROLLUP and CUBE) that also use the grouping aggregate function. As described in the Spark reference guide, grouping(col) indicates whether a specified column in a GROUP BY is aggregated or not, returns 1 for aggregated or 0 for not aggregated in the result set.",
