Move cli-ocm into oc

[danilo-gemoli]

We have been building cli-ocm via a BuildConfig and push it into registry.ci.openshift.org.

Folks use this image into their ci-operator configurations like so:

base_images:
  cli-ocm:
    name: cli-ocm
    namespace: ci
    tag: latest

and the image gets resolved from quay.io/openshift/ci:ci_cli-ocm_latest.

This means that we have to trigger a BuildConfig and then manually push the outcome into quay.io manually, every time someone needs a new version of this image.

By moving it into the ci-operator's openshift/oc configuration, the whole mechanism of building and pushing will be handled entirely by ci-operator.

As a final yet important note: this PR isn't enough by itself.

ci-operator is going to promote the image to:

quay.io/openshift/ci:ocp_4.20_cli-ocm

whereas the base_images (see the snipped right above) pulls it from:

quay.io/openshift/ci:ci_cli-ocm_latest

If we want to go down this route we have to follow this up with another PR and update a bunch of ci-operator configurations, such as the base_images would look like so:

base_images:
  cli-ocm:
    name: "4.20"
    namespace: ocp
    tag: cli-ocm
