      * Previously, if you deleted the `clusterresourceoverride-operator` service or uninstalled the Cluster Resource Admission Override Operator, the `v1.admission.autoscaling.openshift.io` API service was unreachable and prevented needed cluster functionas, such as installing other Operators on the cluster. With this release, a fix ensures that if the Cluster Resource Admission Override Operator is uninstalled, the `v1.admission.autoscaling.openshift.io` API service is also deleted so that the cluster functions are not impacted.

      Description of problem:

      After the clusterresourceoverride-operator executed test case OCP-27070(install clusterresourceoverride-operator, create a ClusterResourceOverride and then delete it), the apiservice v1.admission.autoscaling.openshift.io will become not reachable. As a result, some other operators will not be able to install successfully due to "unable to retrieve the complete list of server APIs:[ admission.autoscaling.openshift.io/v1|http://admission.autoscaling.openshift.io/v1]: stale GroupVersion discovery:"  error.

      Version-Release number of selected component (if applicable):

      4.17.11 + ClusterResourceOverride Operator.v4.17.0-202412170235    

      How reproducible:

      Always

      Steps to Reproduce:

      1. Install ClusterResourceOverride Operator.v4.17.0-202412170235  
2. Create ClusterResourceOverride with below yaml file:
apiVersion: operator.autoscaling.openshift.io/v1
kind: ClusterResourceOverride
metadata:
    name: cluster
    namespace: clusterresourceoverride-operator 
spec:
  podResourceOverride:
    spec:
      memoryRequestToLimitPercent: 50 
      cpuRequestToLimitPercent: 25 
      limitCPUToMemoryPercent: 200 

3. Delete ClusterResourceOverride:
% oc delete ClusterResourceOverride cluster -n clusterresourceoverride-operator

      Actual results:

      After ClusterResourceOverride deleted, the service clusterresourceoverride got deleted, the apiservice v1.admission.autoscaling.openshift.io become not reachable. As a result, some other operators will not be able to install successfully due to "unable to retrieve the complete list of server APIs:[ admission.autoscaling.openshift.io/v1|http://admission.autoscaling.openshift.io/v1]: stale GroupVersion discovery:"  error.

No resources found in clusterresourceoverride-operator namespace.

      Expected results:

      If the operator removes the service, it should also remove the API service. So other operations won't be impacted
