753a350418 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 .
