+++ This bug was initially created as a clone of Bug #1947795 +++

This component accesses APIs that will be removed in 4.9 (Kubernetes 1.22). It is causing the DeprecatedAPIInUse alert to fire in every 4.8 clusters permanently and hence must be fixed in 4.8 (blocker+).

The raw audit data can be found at https://gist.github.com/sttts/50a1429837f2448ce07f30174fa73cdb.

Here are the observed requests for this component:

system:serviceaccount:openshift-cluster-version:default: /apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions/networks.config.openshift.io

system:serviceaccount:openshift-cluster-version:default: /apis/rbac.authorization.k8s.io/v1beta1/clusterrolebindings/default-account-cluster-network-operator

  severity: info
annotations:
  message: Deprecated API that will be removed in the next version is being used. Removing the workload that is using the {{"{{$labels.group}}"}}.{{"{{$labels.version}}"}}/{{"{{$labels.resource}}"}} API might be necessary for a successful upgrade to the next cluster version. Refer to the audit logs to identify the workload.

Different issue from bug 1932165 which is about variable not translated to value

but the api versions are all actually v1, which means apiserver_requested_deprecated_apis may post the wrong result
