* feat: Create provisioner abstraction Creates a provisioner abstraction that takes prior art from the Terraform plugin system. It's safe to assume this code will change a lot when it becomes integrated with provisionerd. Closes #10. * Ignore generated files in diff view * Check for unstaged file changes * Install protoc-gen-go * Use proper drpc plugin version * Fix serve closed pipe * Install sqlc with curl for speed * Fix install command * Format CI action * Add linguist-generated and closed pipe test * Cleanup code from comments * Add dRPC comment * Add Terraform installer for cross-platform * Build provisioner tests on Linux only
