tasks: disable broker heartbeat to workaround connection issues

Browse Source 
I have been seeing repeated emailed errors from Django reporting
"ConnectionResetError: [Errno 104] Connection reset by peer" in the call
to get task status i.e:

File "/opt/layerindex/layerindex/views.py" in task_log_view
  1572.         if result.ready():

Digging around this seems to be some sort of known bug:

https://github.com/celery/celery/issues/4817
https://github.com/celery/celery/issues/4980

The workaround suggested is to disable the broker heartbeat, so try
that in order to avoid the errors.
