Add max I/O time to Hbase runtime stats Collect and display the maximum Hbase operator I/O time. In a parallel plan, this is chosen from the biggest Hbase I/O elapsed time among all the same Hbase tcb instances at the runtime stats merge stage. For serial plan the value equals to the Hbase I/O elapsed time.
In addition, the displayed Hbase I/O is changed from byte to MB.
