API mirroring annotations not registered or documented

[sftim]

This is a Bug Report

Problem: Kubernetes sets up to ~three~ four annotations when mirroring a resource (for example, a mirror pod). These are:

• kubernetes.io/config.source
• kubernetes.io/config.seen
• kubernetes.io/config.hash
• kubernetes.io/config.mirror

However, those annotations are not documented in https://kubernetes.io/docs/reference/labels-annotations-taints/

Proposed Solution: Document those annotations.

Page to Update: https://kubernetes.io/docs/reference/labels-annotations-taints/

Additional Information: See https://pkg.go.dev/k8s.io/kubernetes/pkg/kubelet/types for more details on the values that the kubelet sets for kubernetes.io/config.source. I don't think we promise that the kubelet is the only thing that ever sets this annotation, though.
