Feature request: support buildah

[jbsouvestre]

👋 Hello, thanks for the work on this repo

I'd like to submit a feature request to support builah as an additional engine

I'd be happy to work on a merge request

Hi buddy... Why not use Podman for that? It uses build in the background? 🤔

I have the same request. This is the reason why: https://docs.redhat.com/en/documentation/openshift_container_platform/4.6/html/builds/custom-builds-buildah

We build using Tekton on a OpenShift cluster, hence we'd like to use OpenShift recommended technology.
