Description of problem:
In IPv6 cluster metrics from openshift-controller-manager 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-controller-manager/openshift-controller-manager/0` is DOWN


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