    Rename function relay_update
    
    Rename function to update_command_output() to better reflect that this
    callback updates the UI with the latest output read from the command
    being executed.
    
    This makes more sense knowing a future change will add a separate
    callback which parses the output read from the command and updates the
    progress bar.  This function should be named update_command_progress().
