Bug 2065547: Gather some error messages from the kube-controller-manager containers

[tremes]

Gathers logs from kube-controller-manages conainers including following messages:

• Internal error occurred: error resolving resource
• syncing garbage collector with updated resources from discovery

Steps to reproduce:

1. Create a new namespace called dc-test
2. Get the uuid from the yaml definition of the newly created namespace.
3. Create new DeploymentConfig - you have to pass your uuid there in the ownerReference:

apiVersion: apps.openshift.io/v1
kind: DeploymentConfig
metadata:
  name: example-aaa
  namespace: dc-test
  ownerReferences:
   - apiVersion: v1
     kind: namespace
     name: dc-test
     uid: <PUT YOUR UUID>
spec:
  selector:
    app: httpd
  replicas: 3
  template:
    metadata:
      labels:
        app: httpd
    spec:
      containers:
        - name: httpd
          image: >-
            image-registry.openshift-image-registry.svc:5000/openshift/httpd:latest
          ports:
            - containerPort: 8080

4. Stop the openshift-api with

oc patch openshiftapiservers.operator.openshift.io cluster --type merge --patch '{"spec": {"managementState": "Removed"}}'

5. Delete the dc-test namespace.
6. Start back the API so that you can read the logs (not sure if it's required)

oc patch openshiftapiservers.operator.openshift.io cluster --type merge --patch '{"spec": {"managementState": "Managed"}}'

@jholecek-rh please check

The code fine, and I tested the modified IO on a testing cluster. After performing the described steps, I got a log file with three syncing garbage collector with updated resources from discovery (attempt 1): added: ... errors in the IO archive, so it seems to work as it's supposed to.
