    NSX-mh: perform appropriate pre-delete checks

    This patch ensures that pre-delete checks are executed in the
    appropriate way for both DVR and 'traditional' routers, by
    invoking the _ensure_router_not_in_use method defined in
    neutron.db.l3_db.L3_nat_dbonly_mixin

    Also, verify metadata network before removing router to ensure
    metada access network's router port is removed if not yet
    deleted.
