    Remove get_router_cidrs method of dvr_edge_ha router

    Since commit a388f78c8cb4b1c860bfc11029b5210955f1932d, we fetch
    routers' existing floating ip address from the fip namespace's
    route table instead of qrouter namespace's qg device for the
    dvr_local and dvr_edge router. But for dvr_edge_ha router, it
    still fetch the existing floating ip like legacy router, causing
    it can’t know which existent floating ip rules need to be removed.

    After removing the get_router_cidrs method, the dvr_edge_ha router
    inherit the get_router_cidrs method from dvr_local router and it
    will remove the existent floating ip rules successfully if we
    disassociate the floating ip.
