    Use `undercloud` instead of `Undercloud` when delegating tasks
    
    If ansible detects uppercase characters in delegate_to, it assumes the
    target is a grou, not a host.
    
    We should use all lowercase representation (e.g., `undercloud`) so that
    ansible does the right thing and looks for the host, instead of looking
    for the `Undercloud` group.
