> Given that a series TODO mention {{This is a temporary hack until we have ported the MetricQueryService to the new RpcEndpoint}}, I'd like to give it a try to implement the RpcEndpoint version of MetricQueryService.
> Basically, port {{onRecieve}} to 
> 1. {{addMetric(metricName, metric, group)}}
> 2. {{removeMetric(metric)}}
> 3. {{createDump()}}
> And then adjust tests and replace {{metricServiceQueryPath}} with a corresponding {{RpcGateway}}.
> I'd like to learn that if the statement if true --- when we call a Runnable/Callable with runAsync/callAsync, then the Runnable/Callable is running in the main thread of the underlying RPC service, specifically, in the actor thread?
