Memory Spilling for the Hash Join Operator

Hi Drill developers,

The document should allow commenting, so please add any comment that comes to mind …

This work follows the prior design and implementation of memory spilling for the Hash Aggregate operator (HAG).
If anyone needs to look back, here is the link that old HAG design:
