    DVR: Add forwarding routes based on address_scopes

    When we create agent gateway port on all the nodes irrespective
    of the floatingips we can basically use that agent gateway port to
    forward traffic in and out of the nodes if the address_scopes match,
    since we don't need SNAT functionality if address scopes match.

    If a gateway is configured and if it has internal ports that belong
    to the same address_scopes then no need to add the redirect rules.
    At the same we should also add a static route in the fip namespace
    for every interface that is connected to the router that belongs to
    the same address scope.
