   * `SERVER/SHARE` is the NFS address of your server and share.
   * `VERSION` is the NFS protocol you want to use. For example, if you want to use NFSv4,
  -set the version to `4.1`. Valid values are `3.0`, `4.0`, `4.1` or `4.2`. If no version is

  $ cf create-service nfs Existing SERVICE-INSTANCE-NAME -c '{"share":"SERVER/SHARE", "version":"NFS-PROTOCOL"}'
