NFS testing will automatically be enabled when CephFS is enabled. This makes sure the NFS tests run in the CI where there are different jobs for CephFS and RBD. With a dedicated testNFS variable, it is still possible to only run the NFS tests, when both CephFS and RBD are disabled. Signed-off-by: Niels de Vos <ndevos@redhat.com>
