    Attaches handler(s) and sets log level to the root logger.

    Example usage:

        import logging
        from ulogger import setup_logging

        setup_logging('my_awesome_program', 'INFO', ['stream'])

        logging.info('ohai')

    Args:
        progname (str): Name of program.
        level (str): Threshold for when to log.
        handlers (list): Desired handlers, default 'stream',
            supported: 'syslog', 'stackdriver', 'stream'.
        **kwargs (optional): Keyword arguments to pass to handlers. See
            handler documentation for more information on available
            kwargs.
