> This change introduces a new feature to the flink-metrics-prometheus module, allowing users to specify a whitelist of metrics to be exposed through the Prometheus reporter.
> Previously, all metrics were reported to Prometheus by default. This could lead to performance issues and increased costs in environments with a large number of metrics.
> With this change, users can now configure a whitelist of metrics using the metrics.reporter.
> prometheus.whiteList option. Only metrics whose names are in the whitelist will be reported to Prometheus.
