Refactor the Ceph NFS driver to use Cephadm deployed NFS for OpenStack Shared File Systems Service (Manila)

Add a new protocol helper implementation to consume Cephadm deployed NFS Ganesha. This should make our driver code easier, delegating the NFS Ganesha administration to Cephadm instead to the manila operator as we currently do. Communication with NFS Ganesha will be simplified as well, since we will use the interfa...
