As a user of bedrock, I would like documentation that explains how Bedrock makes it easier for me to deploy and maintain K8s one or many clusters at an infrastructure level with Terraform.

This item covers:

• Pattern: Multiple nearly identical clusters differentiated by only small config changes.
• Pattern: Separating template from implementation and how that enables centralized updates and local applications.
• Practice: Scaffolding
• Practice: Generating
• Practice: Versioning and upgrading underlying templates.
