Part of https://github.com/stackabletech/issues/issues/555

Depends on https://github.com/stackabletech/operator-rs/pull/799

Ensure the ephemeral (listener) volumes attached directly to the datanode containers are labeled with the "recommended labels".

This is now the expected structure:

metadata:
  name: hdfs-datanode-default
spec:
  template:
    volumes:
    - ephemeral:
        volumeClaimTemplate:
          metadata:
            annotations:
              listeners.stackable.tech/listener-class: external-unstable
            creationTimestamp: null
            labels:
              app.kubernetes.io/component: datanode
              app.kubernetes.io/instance: hdfs
              app.kubernetes.io/name: hdfs
              app.kubernetes.io/role-group: default
          spec:
            accessModes:
            - ReadWriteMany
            resources:
              requests:
                storage: "1"
            storageClassName: listeners.stackable.tech
            volumeMode: Filesystem
      name: listener

Stacklet listing now includes datanode endpoints as they inherit the labels of the (listener) ephemeral volumes:
