 Review comment:
   this line is incredibly misleading; based on the naming one would assume that all metrics
are unregistered.

> Since the {{MetricQueryService}} is implemented as an Akka actor, it can only send messages
of a smaller size then the current {{akka.framesize}}. We should check similarly to FLINK-10251
whether the payload exceeds the maximum framesize and fail fast if it is true.
