Bug Description

When using network-manager-openvpn, it always overwrite the default route. There is an option to prevent overwriting the default route, but this also turns off addition of remote DNS information to dnsmasq. This behavior is wrong.

The OpenVPN server pushes an option, redirect-gateway, if it expects the client to change its default route. Although OpenVPN itself pays attention to this, the information is lost in the interface to nm-openvpn-service-openvpn-helper; instead, the helper always forwards the route from route_vpn_gateway up the stack, and NetworkManager always uses it.

Because of this, there is no correct way to configure a client to get remote routes and DNS from the VPN, but not a default route. This is very problematic.
