Would be nice to provide an easy way to enable [BuildKit](https://docs.docker.com/develop/develop-images/build_enhancements/) for faster and more efficient builds. It's as easy as setting `DOCKER_BUILDKIT=1` before using the Docker CLI, not sure what is required from the perspective of the Docker API usage.
