When memcached mode is enabled port isn't automatically opened

[zaphinath]

When we add the args to the dragonfly.yaml like the following it doesn't open that port on the kubernetes service. The operator api doesn't appear to have the ability to custom set ports and port forwarding so not sure what the best approach is to getting the memcached port opened.

  spec:
    args:
    - --memcached_port=11211

and it produces only the following ports on the svc

  ports:
    - name: redis
      nodePort: 30155
      port: 6379
      protocol: TCP
      targetPort: 6379
