Philip Dubé 720525cfda Add support for window functions on coordinator 
Some refactoring:
Consolidate expression which decides whether GROUP BY/HAVING are pushed down
Rename early pullUpIntermediateRows to hasNonDistributableAggregates
Create WorkerColumnName to handle formatting WORKER_COLUMN_FORMAT
Ignore NULL StringInfo pointers to SafeToPushdownWindowFunction
Fix bug where SubqueryPushdownMultiNodeTree mutates supplied Query,
	SafeToPushdownWindowFunction requires the original query as it relies on rtable

Support subqueries in HAVING (#3098) 
Areas for further optimization:
- Don't save subquery results to a local file on the coordinator when the subquery is not in the having clause
- Push the the HAVING with subquery to the workers if there's a group by on the distribution column
- Don't push down the results to the workers when we don't push down the HAVING clause, only the coordinator needs it

Add support for window functions that can be pushed down to worker (#2008) 
This is the first of series of window function work.

We can now support window functions that can be pushed down to workers.
Window function must have distribution column in the partition clause
 to be pushed down.
