    daemon: parameterize create_display
    
    There's some logic in create_display and friends,
    that would be good to reuse for transient displays.
    
    This commit adds a type argument to create_display
    to say what kind of display to create.
    
    Right now it only supports the one type it's always
    supported, but that will change in a follow up commit.
