Infrastructure as code configuration

How to setup

1. Install pulumi binary with curl -fsSL https://get.pulumi.com/ | sh
2. Run pulumi new. Log in via browser and choose a template. I started with github-python.
3. Follow the wizard steps.

After the step-by-step setup, I noticed a couple things that felt unusual in a conda context:

• pulumi handles its own venv when you choose a Python template. It will symlink to the current python in PATH. Instead, we have chosen to bootstrap the environment with pixi so a random interpreter is not chosen on initialization. You just need to run pixi install. We have adjusted the runtime.options.virtualenv path in Pulumi.yaml accordingly. You can also change this to a given conda environment if you want, but I'm not sure if one can use env vars here.
• The Pulumi "programs" (e.g. __main__.py) are located in the repository root by default. I think it's tidier to have them under a subdirectory like src/. This was adjusted in Pulumi.yaml by changing the value of main.

I think Pulumi will still write to requirements.txt here and there, so we have to find a way of keeping pixi.toml in sync to benefit from the lockfiles.

Once there we can start importing repositories, teams and other github resources

Import Github resources

We need pulumi-github in the virtual environment. This should have been added by the pulumi new command already.

This follows https://www.pulumi.com/blog/managing-github-with-pulumi/ with some changes.
