@davidyan74 : Do you not want to calculate this at same window boundaries?
Different leaf operators could be at different windowIds and similarly
different upstream operators for a single leaf operator could be at different
windowIds...
> Reported latency is wrong when a downstream operator is behind more than 1000
> windows

> We should probably estimate this by reporting the latency using the number of
> windows behind when that happens. Right now it reports a stale latency.
