> SlabCache incorrectly reports block count and could do a better job reporting free size.
MetricsRegionServerWrapperImpl incorrectly reports block cache count. Expose Direct Memory
stats on RegionServer WebUI.
> Also clean up javadoc on BlockCache interface methods, and whitespace in cache-related
classes.
