Measure latency/throughput of ReshardingOplogApplier::_applyBatch

• Should collect latency information as a histogram with coarse grained buckets (0-10ms,11-100ms,101-1000ms, 1001-10000ms, 10001+ms)
• Should track total number of invocations that complete
• Should report these metrics in serverStatus to be consumed by FTDC.
• Should report these metrics in currentOp if there is a resharding operation currently in progress.
