    Description : Makes the image bundle tar ball.
    Arguments   : Image name from the command line
                  Destination command line parameter, i.e. name of the tar ball.  For a
                    remote host this can include the target directory.
                  Remote host parameter from the command line, if specified
                  Image attributes from the osimage table
                  callback
                  Current working directory
    Returns     : None
