[IMPROVEMENT] Add basic tooling

[89luca89]

We should have some basic tools to ease the use of the project

Ideally we can gather them in a ./utils folder

Some basic tools can be

• generate_inventory to create a basic inventory from a template, passing arguments to it
• terrible
  • up to easily run the playbook
  • down to shut down VMs preserving resources
  • purge to purge a playbook
  • validate to validate an existing playbook
  • check_deps to check if the system meets all terrible requirements

Open to other ideas
