This change adds a StorageNFS network. It's required by
https://review.openstack.org/#/c/471245 which implements
NFS Ganesha backend for Manila service.
To define and enable the StorageNFS network, deploy using
network_data_ganesha.yaml instead of network_data.yaml.
Besides the former adding the StorageNFS network, these
are otherwise identical.
If enabled it's also necessary to add StorageNFSIpSubnet and
StorageNFSNetworkVlanID heat parameters into network templates.
