> As we begin to include more and more plan-global stuff (such as Scheduler,
> AsyncScheduler, IOScheduler, ExecContext), ExecPlan's definition is becoming
> cluttered. ExecPlan should store and organize nodes, and store these
> structures elsewhere. We thus introduce QueryContext which will store any
> information related to the currently executing plan.
> An added bonus is that now more components can be decoupled from ExecPlan and
> rely only on QueryContext (useful for e.g. testing, or just reusing a
> component in a non-ExecPlan context).
> Also, this QueryContext can introduce options for the query such as maximum
> memory used and this legacy batching thingy.
