The perf conters of mds daemon now only can statistics filesystem op number and the all replay latency.Sometimes we not only want to konw the entire reply time, it's better if we can
dump the latency of all operations which will help we analysis of what kind of operation is the most waste of time.In addition we can statistics the proportion of every operations and
the total time easily.
