    Fix update preview to handle nested stacks

    Currently the update preview code has no support for previewing
    the effect of an update on nested stacks, which I assume was an
    oversight in the original implementation. So this adds a show_nested
    flag to the API which allows enabling recursive preview of the whole
    update including nested stacks.
