> Fix Min/Avg/Max Values for FS Latency Metrics

> Currently RegionServer FS latency metrics are a little deceiving. Because
> fs*Latency is only updated during RegionServerMetrics::doUpdates, you are
> really getting the min/max of the latency average over 'hbase.period' instead
> of the actual min/max outliers. We should refactor the code so we can
> display these outliers and reset them every 'hbase.period'
