Those two loggers completely flood the breadcrumb buffer. I suspect that they "drive out" other events as well. Some people were complaining about junk breadcrumbs in celery from those loggers.

It's possible that we have a bug where we leak breadcrumbs between threads (and that's what's causing this issue), but I don't see how. If so we should see breadcrumbs from other loggers "leaked" between tasks, not just these two celery loggers.

Fix: call ignore_logger for both celery.worker.job and celery.worker.strategy in the celery integration
