See parent for more background, but our healthcheck polling clean up task is leaving a number of builds in an unfinished state. This is because the query is looking specifically for builds where healthcheck!=None, but we are leaving a good number of builds in a state with healthcheck=None:

• Builds: active builds stuck in bad state with healthcheck=None #12474

While we should address the builds being left in a bad state, we should also make sure our healthcheck is catching builds that are not in a known good state and terminating those too.

I mentioned on the parent that we do need to be careful not to mask these bugs by relying on the clean up task to fix problems with the build data. We should address all of these issues.
