### What would you like to be added?

This is just my wishlist. We need all of them, so no specific priority.

- [ ] Regexes for object names, label keys, values, container names, etc. I think this one is already in the works?
- [ ] validate the type metav1.Conditions
- [ ] simple functions to check if conditions are true/false.
- [ ] taints and tolerations
- [ ] labelSelectors (we don't need this one, but it will probably be useful for some projects)
- [ ] The ultimate validation: Pod templates, but worth starting with just containers :) Very useful for job CRDs.
- [ ] ... (waiting for feedback)

### Why is this needed?

As we were working on transitioning Kueue validation webhooks to CEL, we ended up with a lot of repeated validation lines. In some cases, validating something is so involved that we decided to keep most of the webhooks, otherwise readability would be significantly impacted.
