These NFS Controller and Identity servers are the base for the new provisioner. The functionality is currently extremely limited, follow-up PRs will implement various CSI procedures. CreateVolume is implemented with the bare minimum. This makes it possible to create a volume, and mount it with the kubernetes-csi/csi-driver-nfs NodePlugin. DeleteVolume unexports the volume from the Ceph managed NFS-Ganesha service. In case the Ceph cluster provides multiple NFS-Ganesha deployments, things might not work as expected. This is going to be addressed in follow-up improvements. Lots of TODO comments need to be resolved before this can be declared "production ready". Unit- and e2e-tests are missing as well.
