PrometheusMetricsProvider is invalid

[jihwong]

https://bookkeeper.apache.org/docs/reference/config/#statistics
The document indicates that PrometheusMetricsProvider is enabled by default. But it didn't start listening to port 8000.

I also tried to add PrometheusMetricsProvider configuration.
conf

  BK_enableStatistics: "true"
  BK_statsProviderClass: "org.apache.bookkeeper.stats.prometheus.PrometheusMetricsProvider"
  BK_prometheusStatsHttpPort: "8000"
  BK_prometheusStatsHttpAddress: "0.0.0.0"

log

  "statsProviderClass" : "org.apache.bookkeeper.stats.prometheus.PrometheusMetricsProvider",
  "prometheusStatsHttpPort" : "8000",
  "prometheusStatsHttpAddress" : "0.0.0.0",

The default configuration declared on the bookkeeper.apache.org website has been annotated and is invalid. You need to change the configuration

I changed the configuration and the log also printed out that the configuration was successfully loaded, but failed to listen to port 8000

Thank you very much. I can now obtain the metrics information.
PrometheusStatsHttpPort and PrometheusStatsHttpAddress are invalid configurations.
