Create DebOps role template using Copier

I checked out Copier today which is the thing I was waiting for when it comes to project template management as it cannot only do the initial creation, but also update instantiated projects as the template involves (using git history). I propose we create a template for how a DebOps role should look like and use it to keep our roles up-to-date in the monorepo. Currently, Copier has a bug with applying template diffs when the template is not the repo root (https://github.com/copier-org/copier/issues/315). Keep this in mind. It has cost me a bit of time. So I suggest we create a separate repo for now and later merge it into the mono repo.
