Description

currently, they use running counters since the start of the rgw.
should be using a sliding window.
also, the current value is an average, which is susceptible to outliers.
we should add: medain, 90, and 95 percentiles
to have more robust values.

note that this change would require a comment in the release notes, as it changes current behavior.
