manbuyun opened a new pull request #12169:
URL: https://github.com/apache/flink/pull/12169
## What is the purpose of the change
We need to add some custom labels on Prometheus, so we can query by them.
Now we can add jobName\groupingKey to PrometheusPushGatewayReporter in
version 1.10, but not in PrometheusReporter.
Can we add AbstractPrometheusReporter#addDimension method to support this,
so they will be no differences except for the metrics exposing mechanism
pulling/pushing.

notifyOfAddedMetric
