PR testing doesn't happen if the message bus is down

[cgwalters]

coreos/rpm-ostree#709 was pushed a while ago, but no PR status.

Currently @jlebon thinks this is the internal Jenkins getting hung up, and we don't have access to debug/restart it.

The internal message bus is currently down. I filed a ticket to have it investigated. There is only a single point through the event flow at which we still rely on the message bus rather than using it as an optimization with polling fallback. Will work to change that.

Actually, auto branches should still be getting polled and tested. So we should see projectatomic/atomic#966 go through normally.

[jlebon]

(This is not specific to auto branches, just any branch test in general).

[jlebon]

Note that you should still be able to manually trigger a PR test by starting a build of the github-ci-testers-executor job and filling in the GitHub repo and pull id.

This should be resolved now.

Let's use this card to track this work.

This should be fixed now. In the event of the message bus going down, PRs should still be tested within 5 mins.
