WIP: Kubernetes pre-build container

username-removed-357684 requested to merge jayme-github/gitlab-runner:kubernetes_preBuiltContaier into master

What does this MR do?

It uses the predefined images for Pre-/Post-Build steps (like docker executor does) as sidecar container for the runner Pods.

I need some help in how to handle the predefined images. In docker executor has them embedded but I don't think this is possible for kubernetes. Is there any reason to not push the predefined images to Docker Hub and pull from there? This is what I did for testing:

for arch in arm x86_64; do
  wget https://gitlab-ci-multi-runner-downloads.s3.amazonaws.com/master/docker/prebuilt-$arch.tar.xz -O /tmp/prebuilt-$arch.tar.xz
  docker import prebuilt-$arch.tar.xz jaymedh/gitlab-ci-runner-prebuild-$arch:latest
  docker push jaymedh/gitlab-ci-runner-prebuild-$arch:latest
done

Why was this MR needed?

It removes the need to have git and Gitlab-Runner binary in the user images. Thus makes it easier to run builds on user provided images.

Are there points in the code the reviewer needs to double check?
