Description of problem:
In IPv6 cluster metrics from kube-controller-manager-operator cannot be scraped due to connection refused error

Version-Release number of selected component (if applicable):
4.3.0-0.nightly-2019-12-18-145749-ipv6.1

How reproducible:
Always

Steps to Reproduce:
1. Start a cluster
2. Go to prometheus UI -> targets (this needs to be done with port-forward, due to https://bugzilla.redhat.com/show_bug.cgi?id=1788135, cmd: "-n openshift-monitoring port-forward svc/prometheus-operated 9090")

Actual results:
`openshift-kube-controller-manager-operator/kube-controller-manager-operator/0` is DOWN


Expected results:
`openshift-kube-controller-manager-operator/kube-controller-manager-operator/0` is UP

Confirmed with payload 4.4.0-0.nightly-2020-03-23-010639, the issue has fixed:

1) one terminal use command:
`oc -n openshift-monitoring port-forward svc/prometheus-operated 9090`

2) Second terminal check:
[root@dhcp-140-138 ~]# curl -s http://localhost:9090/api/v1/targets  | jq  | grep "openshift-kube-controller-manager-operator/kube-controller-manager-operator/0" -C20 | grep "health"
        "health": "up"
