   ### Jira
   
     - https://issues.apache.org/jira/browse/AIRFLOW-3782
   
   ### Description
   
   Celery supports `autoscale` by accepting values in format `max_concurrency,min_concurrency`.
   But the default value in `default_airflow.cfg` is wrong, and the comment can be clearer.
   
   Reference: http://docs.celeryproject.org/en/latest/reference/celery.bin.worker.html#cmdoption-celery-worker-autoscale

> The default value in default_airflow.cfg is `{color:#6a737d}#{color}{color:#6a737d} worker_autoscale = 12,16{color}`.
> It's somehow misleading and user may just change it in-place in a "minimum,maximum" style while Celery only supports formats like "{color:#333333}--{color}autoscale{color:#333333}={color}{color:#0000dd}10{color},{color:#0000dd}3{color}". i.e. it should be "{color:#3e4349}max_concurrency, min_concurrency{color}".{color:#0000dd}
> {color}
