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.
