    BGPVPN OVS: defer gw ARP redirection until we really need it

    Doing this ARP redirection currently prevents sending traffic
    to a Neutron router connected to the network. We need to avoid
    that if there is no BGPVPN association.

    (we currently accept this drawback when there is a BGPVPN network
    association, since we don't see a use case where a VM would need,
    via a same network, to reach other VMs on other networks, and BGP
    VPN destinations)
