-----------------------------------------------------------------

* IndexRebuildTaskIT does not fail for me (in 4.x-HBase-1.4) with the patch. It does fail
(with or without patch) in 4.x-HBase-1.5 and master).
 * MutableIndexSplitForwardScanIT does not fail either (4.x-HBase-1.4) with the patch... Wait
it's disabled in 4.x

> 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}}.
