    HA-non-DVR router don't need manually add static route

    When a router set as HA mode, The keepalived process will take over
    the route entry's generation. So, the codes that add static route
    is redundant.

    But, for DVR-HA router, in dvr_snat node the keepalived process run
    in snat-namespace and don't take over qrouter-namespace, so the
    manually add static route codes still need be called.
