reserved labels of CustomResourceStateMetrics are getting overwritten

[bavarianbidi]

What happened:

Contrary to the current documentation

NOTE: The group, version, and kind common labels are reserved, and will be overwritten by the values from the groupVersionKind field.

these fields won't get overwritten.

I have following configuration from cluster-api

    metricNamePrefix: capi_kubeadmcontrolplane
    metrics:
    - name: info
      help: Information about a kubeadmcontrolplane.
      each:
        info:
          labelsFromPath:
            version:
            - spec
            - version
        type: Info

but the generated metric will look like the following:

capi_kubeadmcontrolplane_info{cluster_name="glippy",group="controlplane.cluster.x-k8s.io",kind="KubeadmControlPlane",name="glippy",namespace="org-giantswarm",uid="bd2c772e-2140-480f-a051-3ecedc2ed02b",version="v1.22.7"}

What you expected to happen:

capi_kubeadmcontrolplane_info{cluster_name="glippy",group="controlplane.cluster.x-k8s.io",kind="KubeadmControlPlane",name="glippy",namespace="org-giantswarm",uid="bd2c772e-2140-480f-a051-3ecedc2ed02b",version="v1beta1"}

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

I've created #1942 as an alternative approach for the auto-generated group,version and kind labels. I've also created a tracking issue on kubernetes-sigs/cluster-api.

Environment:

• kube-state-metrics version: 2.7.0
• Kubernetes version (use kubectl version): 1.24.4
• Cloud provider or hardware configuration:
• Other info:
