The TransportNodeUsageStatsForThreadPoolsAction now takes the max latency of any task currently queued in the write thread pool queue AND the previously collected max queue latency of any task dequeued since the last call. This covers the possibility that queue times can rise greatly before being reflected in execution: imagine all the write threads are stalled. Adds additional IT testing to exercise both forms of queue latency, a followup for ES-12316.
