Upgrade celery worker options for compatibility with celery 5
- reorder --app to come after the
celery
command - drop --without-* which are buggy currently (and not really useful for this environment). See https://github.com/celery/celery/pull/6365.
(also sneak in "Ignore tests pycache directory")
Test Plan
rebuild the docker image, then doco up
and see the workers actually
starting and doing some work
