[jira] [Created] (AIRFLOW-687) Gracefully halt workers through CLI

Paul Zaczkieiwcz created AIRFLOW-687:
----------------------------------------

             Summary: Gracefully halt workers through CLI
                 Key: AIRFLOW-687
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-687
             Project: Apache Airflow
          Issue Type: Bug
            Reporter: Paul Zaczkieiwcz
            Priority: Minor


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.
