    fix storage.yaml to write environments/storage/nova-nfs.yaml

    753a3504184d966c63121ca95bc0135afbc83a75 removed ceph entries
    from sample-env-generator/storage.yaml which resulted in nova-nfs
    and cinder-netapp-config to be in the same section. Therefore
    environment_generator.py did not update the nova-nfs.yaml .

    Also add quotes to the nfs version as they are required in
    the resulting nova-nfs.yaml .

    Closes-Bug: #1825374
