IMPALA-2076: Correct execution time tracking for DataStreamSender. DataStreamSender uses multiple channels (each channel uses one thread) to send data. We want to know the active wall-clock network time used by DataStreamSender no matter how many threads are used so we only count concurrent sending time and row batch serialization time. We don't want to count recv_TransmitData() time because it is mainly to wait for receiver to deserialize data and process data, not using much network, plus those part are already tracked by Exchange node. Added a ConcurrentStopWatch class to get concurrent transmit time. If a thread is already running, the following thread won't reset the stop watch. And the stop watch is stopped only after all threads finish their work.
