Some outdated references to Terraform and OpenStack were missed during
the project quickstart. These are legacy elements inherited from OpenFun.
This commit cleans up the codebase.
Tilt is a tool for local Kubernetes development.
It makes it easy to see your changes as you
make them, and it rebuilds and redeploys
your app as you change it.
Used https://github.com/openfun/joanie as boilerplate, ran a few
transformations with ChapGPT and adapted models and endpoints to
fit to my current vision of the project.
