Average size of sstables read per request is 10 on my tests with and without
counters, ABSC still show better results comparing to TMBSC.

> CollactionController can construct a factory on init based on mutableColumns
> parameter. ArrayBackedSortedColumns proven to be better for counters as well
> as normal columns (row size from 5 to 75 columns). CFS.getRawCachedRow would
> copy key byte array each time it contracts a RowCacheKey so we want to avoid
> that where possible.
