Add rook-cephfs storage class for filesystem PVCs

[rmohr]

If rook-ceph gets enabled, it can now used for filesystem PVCs.

$ kubectl.sh get storageclasses
selecting docker as container runtime

Also bumping the centos-stream base version, since for the initrd of the older kenerl we don't have kernel modules anymore.

I am unsure regarding to allowing resize and if we should make the fs storage class the default.

Awesome!

The only suggestion I have is that we add a ready check for cephfs similarly to

kubevirtci/cluster-provision/k8s/1.23/rook-ceph.sh

Line 23 in ab5a0f2

until kubectl --kubeconfig /etc/kubernetes/admin.conf get cephblockpools -n rook-ceph replicapool -o jsonpath='{.status.phase}' | grep Ready; do

Just from curiosity why is it needed?

[rmohr]

We provide the kernel from outside the VM. From time to time the kernel module package does no longer exist in the repos anymore and we have to bump to a newer image to use, where we can still find the matching modules in the repo. Let me add it to the commit message.
