Should we reset after snapshot in MutableHistogram?

Current MutableHistogram do not reset after snapshot, so we affect by
historical data. For example when i monitor the queueCallTime, i see one
host's queueCallTime metric is high, but when i trace the host's
regionserver log i see the queueCallTime has been lower, but the metric is
still high.

a mistake, queueCallTime  should be QueueCallTime_mean
