[Bug 1153077] Re: rabbitmq queue fills up and celery stops executing tasks when upload_dhcp_leases is done every minute (by default)

I've recently seen a somewhat similar situation:

- Celery went down for a while.

- Celerybeat jobs accumulated in RabbitMQ.

- When Celery came back up, it spun manically, going through hundreds of
old jobs.

However, neither Celery nor RabbitMQ showed signs of falling over. They
were just busy.

It's a separate bug, but we should ensure that Celerybeat jobs have a
very short lifetime. Maybe RabbitMQ or Celery have a mechanism for
ignoring old jobs. If not, we can add a timestamp check to the job
implementations themselves.
