Description

Distributions and gauge metrics are not visible at Flink dashboard neither Prometheus IO.

I was able to debug the runner code and see that these metrics are being update over FlinkMetricContainer#updateDistributions() and FlinkMetricContainer#updateGauges() (meaning they are treated as "attempted metrics") but these are not visible when looking them over the Flink Dashboard or Prometheus. In the other hand, Counter metrics work as expected.
