    cells: add debug logging to bdm_update_or_create_at_top

    The method is racy and we need to know which conditions we're hitting
    when we fail, which is happening sometimes with the
    test_create_ebs_image_and_check_boot test in Tempest.

    We fail because the image snapshot metadata has duplicate BDM entries in
    it so that when we boot an instance from that image, there are multiple
    BDMs with the same boot_index and nova.compute.api.API._validate_bdm
    throws up.
