    DVR: Cleanup the stale snat redirect rules in router namespace

    After the stale snat namespace is deleted the snat redirect rules
    in router namespace should be cleaned.

    Here we are basically reading the ip rule from the router namespace
    and just cleaning up all the snat redirect rules leaving the default
    ones untouched.
