    unknown kube version unit test: set system mode as duplex

    This change https://opendev.org/starlingx/config/commit/8c359198c8fc1d811d15f98fa3546fbfbd247d69
    added a condition to mark kube versions to be available if they
    are newer than the current version for AIO-SX.

    The unit test to ignore unknown kube version fails intermittently
    due to this change.
    One such run: https://zuul.opendev.org/t/openstack/build/e2387230c96c4069bca14b3ae3532e7f

    Setting system mode as duplex will never let
    the unit test fail.

    Test Plan:
    PASS: All unit tests pass
