Unrelated to the above, we had a question about after-the-fact figuring out what instance type a given step (running in k8s via argo workflows) was running on. We've gotten more aggressive about GCing old pods but belatedly realized that the kubernetes annotations (like instance-type) on the pod were the only way to find that info. Is there some approved method for saving some k8s pod annotations along with a given step results?
