NetworkManager ip route in openVPN config
With custom routes in a custom ovpn file, NetworkManager reports with
`Error: configuration error: unsupported 1th argument to "route" which looks like a FQDN but only IPv4 address supported (line XX)`
Looks like the `route` config option is not available in NM ovpn config but the alternative `route-data` can be used.
The syntax remains the same:
`route-data IP netmask gateway`
