After branching of a new OCP release, create CI jobs for openshift/build-machinery-go for that release.

Typically, something like this.

We use commitchecker, built from openshift/build-machinery-go, in our CI jobs. Its image lives in `ci` namespace and thus DPTP team won't update -master.yaml for a new release and won't create a new release-4.y.yaml. We must do it manually. And it's us, because nobody else cares.
