A new Hetzner cloud project has been created called "Sandbox". This
project is meant for non-production workload which must be created
on-demand from e.g. a CI pipeline. The first project using the sandbox
is aurweb, which wants to use GitLab's Review apps[1] feature to create
dynamic environments on-demand.

Two API tokens have been created, one for the infrastructure project (to
be used by packer) and for the aurweb project.
