Bug 2012902

Verified in OCP 4.10.0-0.nightly-2021-10-16-173656 with Kury on top of OSP RHOS-16.1-RHEL-8-20210916.n.0.

Verification steps:

## When a pod is in 'Completed' state, the Neutron port assigned to it remains in 'Active' state:
>$ oc get pods -n openshift-kube-apiserver -o wide | grep "NAME\|Completed" | head -n 2
>NAME                                       READY   STATUS      RESTARTS   AGE     IP              NODE                    NOMINATED NODE   READINESS GATES
>installer-10-ostest-sccdp-master-0         0/1     Completed   0          18h     10.128.89.131   ostest-sccdp-master-0   <none>           <none>

>$ openstack port list | grep "Name\|10.128.89.131"
>| ID                                   | Name                                            | MAC Address       | Fixed IP Addresses                                                                     | Status |
>| 8b6db073-f109-4b9d-b478-6664ffe11aa2 |                                                 | fa:16:3e:ee:f1:c4 | ip_address='10.128.89.131', subnet_id='57b279bc-259e-4a01-832d-581c6f780042'           | ACTIVE |


## Ports are reassigned to a new Pod if the namespace and the node are the same as the 'Completed' Pod:
>$ oc get pods -n openshift-kube-apiserver -o wide | grep "NAME\|10.128.89.131"
>NAME                                       READY   STATUS      RESTARTS   AGE     IP              NODE                    NOMINATED NODE   READINESS GATES

## Verify in several different namespaces - deploy new "demo" pods and make sure that ports of 'Completed' Pods are reassigned. Using the following sh:

```
completed_pods_addresses=$(oc get pods -A -o wide | grep Completed | awk '{print $7}' | grep -v "ago")
running_pods_addresses=$(oc get pods -A -o wide | grep Running | awk '{print $7}' | grep -v "ago")
openstack port list > osp_port_list
for completed_address in $completed_pods_addresses
do
        cat osp_port_list | grep $completed_address
        for running_address in $running_pods_addresses
        do
                if [ "$completed_address" == "$running_address" ]
                then
                        echo "Reused port found! The port with the following ip address - ${completed_address}."
                fi
        done
done
```
