> This is to account and report total size of region data identified as cold by
> the Time Based Priority logic in the region metrics. We should also expose it
> in the RS UI, as we do have a "% Cached" field, it would help distinguish
> when a low cache ratio is legit (due to time based priority), from when it's
> indeed a caching management problem.
