> The ConfigParser class we base our config parser on can optionally accept a fallback argument:
> {code:python}
> conf.get('sect', 'key', fallback='default')
> {code}
> but our sub-class doesn't support this. It would be nice if we did. Then we can turn
> {code:python}
> plugins_folder = configuration.conf.get('core', 'plugins_folder')
> if not plugins_folder:
>     plugins_folder = settings.AIRFLOW_HOME + '/plugins'
> {code}
> in to this:
> {code:python}
> plugins_folder = configuration.conf.get('core', 'plugins_folder', fallback=settings.AIRFLOW_HOME + '/plugins')
> {code}
