fix: Update runservice worker scripts to disable unneeded features

[baumandm]

We've encountered issues where workers would stop receiving tasks after an error message like this:

consumer: Connection to broker lost. Trying to re-establish the connection...
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/celery/worker/consumer/consumer.py", line 332, in start
    blueprint.start(self)

I was able to reproduce this locally via Docker by manually bouncing the Redis container.

After some research, we came across suggestions to disable the heartbeat/gossip/mingle features of Celery. In my local testing it appears this change eliminates (or at least reduces) the issue where the workers cannot reconnect to Redis after a connection failure.

We have been running this in production for over a month and everything works as expected, including Flower.
