Aurweb wants to use terraform to create VMs in the Hetzner cloud sandbox
project and it must store the terraform state somewhere. The state can
be stored in GitLab[1], but unfortunately the access is not very
granular. So to avoid handing the CI pipeline too much access to the
aurweb project, a new project has been created, to store only the
terraform state, and an associated project access token.
