DRILL-5737: Hash Agg uses more than the allocated memory under certain low memory conditions Note: Provide a new config parameter HASHAGG_FALLBACK_ENABLED which is set to true by default. When 2 Phase HashAgg doesn't have enough memory to hold 2 partitions then based on this flag it either fallsback to old behavior of consuming unbounded memory or it fails the query.
