Inconsistent storage configuration

[flozanorht]

The demo configures an NFS server on bastion and creates manually provisioned PVs that refer to file shares on that NFS server at
https://github.com/rh-osp-demo/dp-demo/blob/main/demo/create-cp.md#create-a-nfs-share-for-cinder

But later, the demo deploys a control plane which references ODF storage classes:
https://github.com/rh-osp-demo/dp-demo/blob/main/demo/create-cp.md#finally-create-the-openstack-control-plane

See the contents of osp-ng-ctlplane-deploy.yaml :

apiVersion: core.openstack.org/v1beta1
kind: OpenStackControlPlane
metadata:
name: openstack-galera-network-isolation
spec:
secret: osp-secret
storageClass: ocs-storagecluster-ceph-rbd

Indeed, the demo environment now includes both the predefined ODF storage classes and my new nfs storage class

# oc get storageclass

ocs-storagecluster-cephfs               openshift-storage.cephfs.csi.ceph.com   Delete          Immediate              true                   3d5h
openshift-storage.noobaa.io             openshift-storage.noobaa.io/obc         Delete          Immediate              false                  3d5h

But if I have ODF available in the demo environment, there's no need to use nfs from OpenShit, for OpenStack control plane services or whatever else I deploy in that OpenShift cluster.
