Service exposition with ListenerClasses

Apache Hive offers an API. The operator deploys a Listener for the Metastore pods.

The listener defaults to only being accessible from within the Kubernetes cluster, but this can be changed by setting .spec.metastore.roleConfig.listenerClass:

spec:
  metastore:
    roleConfig:
      listenerClass: "cluster-internal" (1)
    roleGroups:
      default:
        replicas: 1

1	Specify one of `external-stable`, `external-unstable`, `cluster-internal` (the default setting is `cluster-internal`).
