dedicated actor system
URL: https://github.com/apache/flink/pull/6759#issuecomment-427786350
 
 
   Thanks for updating this PR @Clarkkkkk. I'll give it a pass later today. 
   
   I think we should not instantiate the `ActorSystem` inside of the `MetricRegistry` and
instead pass it in. That way we are flexible where the `QueryMetricServiceActor` is running.
E.g. in other setups it might be acceptable to share an `ActorSystem` with another component.

> In order to make the {{MetricQueryService}} run independently of the main Flink components,
it should get its own dedicated thread pool assigned.
