> The per-CF "getsize" metric's intent was to track bytes returned (to HBase clients) per-CF.
[Note: We already have metrics to track # of HFileBlock's read for compaction vs. non-compaction
cases -- e.g., compactionblockreadcnt vs. fsblockreadcnt.]
> Currently, the "getsize" metric gets updated for both client initiated Get/Scan operations
as well for compaction related reads. The metric is updated in StoreScanner.java:next() when
the Scan query matcher returns an INCLUDE* code via a:
>  HRegion.incrNumericMetric(this.metricNameGetsize, copyKv.getLength());
> We should not do the above in case of compactions.
