Description of problem:

When an IngressController specifies a namespace selector, the router pod prints a log message indicating that it will filter namespaces using that selector.  However, the log output does not print the label selector correctly.


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

4.6.0-0.ci-2020-08-06-061328

Most likely introduced in 4.3 by https://github.com/openshift/router/pull/47/commits/dc68ebfcbd9fdc600391ebe050228534dd2b07c3.


How reproducible:

Consistently.


Steps to Reproduce:

1. Launch a 4.6 cluster.

2. On the cluster created in Step 1, create a new IngressController that specifies spec.namespaceSelector:

     oc apply -f - <<'EOF'
     apiVersion: operator.openshift.io/v1
     kind: IngressController
     metadata:
       name: namespace-selector
       namespace: openshift-ingress-operator
     spec:
       replicas: 1
       domain: xyz.com
       endpointPublishingStrategy:
         type: Private
       namespaceSelector:
          matchLabels:
            foo: bar
     EOF

3. Check the logs for a router pod for the IngressController created in Step 2:

    oc -n openshift-ingress logs -c router deployments/router-namespace-selector


Actual results:

The log output prints the label selector incorrectly:

    "msg"="router is only using routes in namespaces matching labels"  "labels"=[{}]


Expected results:

The log output prints the label selector correctly:

    "msg"="router is only using routes in namespaces matching labels"  "labels"="foo=bar"
