> Brought to light in part in PHOENIX-5109, plan selection in Phoenix is too
> complicated with its logic spread over multiple areas. My recent changes let
> most index through the initial filters and next step is to put all the logic
> in {{QueryOptimizer.orderPlansBestToWorst}}.
> One exception is plans with global indexes for queries with uncovered
> queries, those should still be handled in {{addPlan}}.
