Please add a brief PR description. Is this for showing the required resources on each WorkerActor in its corresponding the dashboard row?

hold off on reviewing for now. Just creating a PR to generate a wheel and do some manual testing

Looks like one of the issues is that the train run doesn't exist in the state actor until after it gets scheduled.

I need to know these required resources before so if there are issues scheduling the placement group, we can identify the autoscaler logs relevant to those scheduling issues.

Something we should capture with properly with the schema for TrainV2.
