    Description

      Description of problem:

      The reconciler removes the overlappingrangeipreservations.whereabouts.cni.cncf.io resources whether the pod is alive or not.

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

       

      How reproducible:

      Always

      Steps to Reproduce:

      1. Create pods and check the overlappingrangeipreservations.whereabouts.cni.cncf.io resources:

      $ oc get overlappingrangeipreservations.whereabouts.cni.cncf.io -A
NAMESPACE          NAME                      AGE
openshift-multus   2001-1b70-820d-4b04--13   4m53s
openshift-multus   2001-1b70-820d-4b05--13   4m49s

      2.  Verify that when the ip-reconciler cronjob removes the overlappingrangeipreservations.whereabouts.cni.cncf.io resources when run:

      $ oc get cronjob -n openshift-multus
NAME            SCHEDULE       SUSPEND   ACTIVE   LAST SCHEDULE   AGE
ip-reconciler   */15 * * * *   False     0        14m             4d13h

$ oc get overlappingrangeipreservations.whereabouts.cni.cncf.io -A
No resources found

$ oc get cronjob -n openshift-multus
NAME            SCHEDULE       SUSPEND   ACTIVE   LAST SCHEDULE   AGE
ip-reconciler   */15 * * * *   False     0        5s              4d13h

       

      Actual results:

      The overlappingrangeipreservations.whereabouts.cni.cncf.io resources are removed for each created pod by the ip-reconciler cronjob.
The "overlapping ranges" are not used.

      Expected results:

      The overlappingrangeipreservations.whereabouts.cni.cncf.io should not be removed regardless of if a pod has used an IP in the overlapping ranges.
