Review Comment:
   Seems the loggerSink is a safety measures to help cleanup the timeMetrics, 
if the `getMetrics` is not called for long time.
   
   For our use case, we have a sidecar agent to collect celeborn metrics 
periodically, and we do not need to enable this feature.
   
   could you highlight it in the ConfigEntry docs or migration guide?
