[SPARK-9817][YARN] Improve the locality calculation of containers by taking pending container requests into consideraion
This is a follow-up PR to further improve the locality calculation by considering the pending container's request. Since the locality preferences of tasks may be shifted from time to time, current localities of pending container requests may not fully match the new preferences, this PR improve it by removing outdated, unmatched container requests and replace with new requests.
sryza please help to review, thanks a lot.
