> This tracks introducing the basic concepts of tuple caching. Specifically, it
> should introduce the TupleCacheNode, which is an ExecNode that can be placed
> in a plan to cache tuples between existing nodes in the plan. The
> TupleCachePlanner should place these nodes in locations that are eligible.
> The TupleCachePlanner is responsible for eligibility as well as producing a
> cache key.
