Jérôme Petazzoni b6340acb6e ⚛️ Huge refactoring of lab environment deployment system
Summary of changes:
- "workshopctl" is now "labctl"
- it can handle deployment of VMs but also of managed
  Kubernetes clusters (and therefore, it replaces
  the "prepare-tf" directory)
- support for many more providers has been added

Check the README.md, in particular the "directory structure";
it has the most important information.
