Description

HRegion right now has the responsibility of storing static counts and latency numbers for use by the metrics package. Since these maps are incremented and set from lots of places it makes adding functionality hard.

So move the metrics functionality into SchemaMetrics making it more than just a class for naming. The next step will be to simplify the api exposed so that using it will be easier.
