Description of problem

The keepalived-ipfailover component in https://github.com/openshift/images/tree/master/ipfailover/keepalived is used only for on-premise clusters (such as bare metal), but the openshift/images repository does not have any CI jobs that install on-premise clusters, meaning that we are missing CI testing for changes to the component.

Version-Release number of selected component (if applicable)

All versions.

How reproducible

100%.

Steps to Reproduce

1. Open a PR in https://github.com/openshift/images and check which CI jobs are run on it.
2. Check the job definitions in https://github.com/openshift/release/blob/master/ci-operator/jobs/openshift/images/openshift-images-master-presubmits.yaml.

Actual results

There are "ci/prow/e2e-aws", "ci/prow/e2e-aws-upgrade", and "ci/prow/images" jobs defined, but no "e2e-metal" job.

Expected results

There should be a "ci/prow/e2e-aws-metal-ipi" job or similar, and this job should install a bare-metal cluster that uses keepalived-ipfailover.

Additional info

The lack of a CI job came up on https://github.com/openshift/images/pull/161.
