To Reproduce Steps to reproduce the behavior:

We need to update the list of supported stores with RHOSO 18, we currently have

• RADOS Block Device (RBD) is the default back end when you use Red Hat Ceph Storage. For more information, see Configuring the control plane to use the Red Hat Ceph Storage cluster.
• Block Storage (cinder).
• Object Storage (swift).
• S3.
• NFS.
• RBD multistore. You can use multiple stores with distributed edge architecture so that you can have an image pool at every edge site.

Expected behavior

We added distributed zones support in FR2 for Ceph and FR3 for third party therefore we need to change:

• RBD multistore. You can use multiple stores with distributed edge architecture or distributed zones so that you can have an image pool at every edge site or zone.

And add:

• Block Storage (cinder) multistore. You can use multiple stores with distributed zones so that you can have an image pool in every zone.
