This revamps code quite a bit. Series handling has been moved into the gerrit client, it also handles caching. The Runner logic itself has been greatly simplified. The runner logic has been moved into the runner.go, submitqueue.go is gone. The "per-run result object" concept has been dropped - we instead just use annotated logs. Also, we switched to apex/log
