> When deploying a new set of airflow DAGs, it is useful to gracefully shut down all airflow services and restart them.  This allows you to pip install requirements for your DAGs in a virtual environment so that you're sure that your DAGs don't contain unmet dependencies.
> Trouble is, if you kill the celery workers then they'll drop their current task on the floor. There should be a CLI option to gracefully shut down the workers so that deploy scripts can restart all services without worrying about killing the workers.
