Annotation resource.kubernetes.io/pod-claim-name not registered or documented

[sftim]

This is a Bug Report

Problem: The annotation resource.kubernetes.io/pod-claim-name is unregistered, but used in Kubernetes code.

The code comment says:

	// podResourceClaimAnnotation is the special annotation that generated
	// ResourceClaims get. Its value is the pod.spec.resourceClaims[].name
	// for which it was generated. This is used only inside the controller
	// and not documented as part of the Kubernetes API.

However, we don't have a mechanism to register annotations that are not also documented. So, it needs registering.

Proposed Solution:
Register the annotation, by mentioning it in Well-Known Labels, Annotations and Taints.
