We need some alerts so we know if mjolnir starts misbehaving:
- The bulk updates run once a week and take a day or two to load. If the kafka consumer lag gets to 3 days then something is wrong
- document update result="failed" should stay at 0, if it doesn't then something is wrong: https://grafana.wikimedia.org/d/000000591/elasticsearch-mjolnir-bulk-updates?orgId=1&from=now-30d&to=now
