<p>Class that keeps track of a rolling window sum.</p>
<p>For use in tracking recent performance of the connector.</p>
<p>Intended to be similar to
org.apache.beam.sdk.util.MovingFunction(…, Sum.ofLongs()), but for
convenience we expose the count of entries as well so this doubles as a
moving average tracker.</p>
