This is intended to create our own custom build pod via BuildController which will be used as a fallback if the OpenShift Build API is unavailable. The productionized BuildController will use the interface discussed in MCO-563 to interface with this new custom build pod implementation. As a first-pass, we can use the OS image since it has Podman on it.

A future consideration (out-of-scope for this card) is using a dedicated Buildah image (e.g., quay.io/buildah/stable:latest), which should be versioned and managed via the OpenShift release manifest mechanism.

Done When:

• The productionized BuildController has a drop-in way to use custom build pods instead of the OpenShift Build API.
• We may want to expose a knob that will let us explicitly select this custom build pod for testing purposes, though we can later remove it.
