Add a WLM ClusterRole that can also access some NNF resources (#180)

When access to NNF resources is desired, then the WLM would use this
ClusterRole rather than the one provided by DWS.

 The WLM should then use the kubeconfig file associated with this "flux" user to access the DataWorkflowServices API and the Rabbit system.
