Description
The cache stats of past n periods, such as SumHitCountsPastNPeriods, SumHitCachingCountsPastNPeriods, etc,
are useful to indicate the real-time read load of region server, especially for temporary read peak. It is helpful to add such metrics to BlockCache#Stats tab of region server status page. Discussion and suggestion are welcomed.
