   Metrics are not exposed via the listener service and are - as previously - only available within the cluster.
   The service naming has been changed to reflect this.

 * *Apache HBase:*:
   Coordinator Listener classes are now declared at role level `spec.<role>.config.listenerClass` instead of `spec.clusterConfig.listenerClass`.
   HBase has been patched so that the URLs in the UI screens now use listener endpoints (which are externally reachable as long as the appropriate listenerClass has been selected).

   Introduces a listener service on the `metastore` role level.
   Additionally, a `-headless` service for internal communications as well as a `-metrics` service for monitoring is introduced at the role group level.

 * *Apache Spark:*
   The history server UI is now exposed using listeners instead of services created by the operator directly.
   This implementation also changed the CRD by moving the `spec.clusterConfig.listenerClass` field to `spec.node.config.listenerClass`.
   The new and experimental Spark connect servers in this release are also exposed using listeners in the same fashion as the history server.
