Shows how terraform modules and workspaces can live in the same repository, while also having each workspace depend on different versions of those modules.

• 10-development - network v3, cluster v3
• 20-staging - network v2, cluster v2
• 30-production - network v2, cluster v1

• ./init.sh - run whenever you change the versions used by a workspace
• ./apply.sh - apply everything
• ./show.sh - view the created resources (just dummy files).

Terraform will clone the whole repository for each module, e.g. 10-development/.terraform/modules/network and 10-development/.terraform/modules/cluster will both contain the whole repository.

This could be an issue for large projects.
