Description of problem:
In IPv6 cluster metrics from service-catalog-apiserver-operator & service-catalog-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-service-catalog-apiserver-operator/openshift-service-catalog-apiserver-operator/0` is DOWN
`openshift-service-catalog-controller-manager-operator/openshift-service-catalog-controller-manager-operator/0` is DOWN


Expected results:
`openshift-service-catalog-apiserver-operator/openshift-service-catalog-apiserver-operator/0` is UP
`openshift-service-catalog-controller-manager-operator/openshift-service-catalog-controller-manager-operator/0` is UP
Comment 1 Jesus M. Rodriguez 2020-02-26 23:39:42 UTC 
Bumped library-go to pull in the fix for Bug 1788521.
PR: openshift/library-go#657

The default bind network was tcp4, library-go switch it to tcp
which will support ipv6.

The bug states the following:

   We use SetRecommendedServingInfoDefaults() in library-go across
   all operators to provide defaults for API servers that those
   operators run to serve metrics and healthz

Also pinned openshift/api & openshift/client-go to match the release.

cv:4.4.0-0.nightly-2020-03-23-010639
ipv6 cluster

test result:
The targets of openshift-service-catalog-apiserver-operator and openshift-service-catalog-controller-manager-operator in Prometheus UI are "up".
