This creates a jinja-init image based on https://github.com/ObjectifLibre/jinja-init We can use this image as an "init container" in k8s to template out config files using configmaps and secrets. It also adds a gitea-init Dockerfile, which will require the jinja-init image to be published first. Change-Id: I88e14c4f0d868f99aa0a0316e6b9e24c2a8fea68
