Describe the feature

We would like to track Cloudformation templates that use the Blueprint Property Injection feature.

In the applyInjectors function (before this line https://github.com/aws/aws-cdk/blob/main/packages/aws-cdk-lib/core/lib/prop-injectors-helpers.ts#L22), I would like to add the following code to update the Stack's metadata to show that Blueprint Property Injection took place.

const stack = Stack.of(scope);
stack.addMetadata('@amzn/aws-cdk-lib-blueprint', 'Y');

Use Case

This will prefix the Cloudformation Template with:

"Metadata": {
    "@amzn/aws-cdk-lib-blueprint": "Y"
  },

This will allow us to track CFN templates that use Blueprint property injection.

Proposed Solution

Add these two lines in applyInjectors.

const stack = Stack.of(scope);
stack.addMetadata('@amzn/aws-cdk-lib-blueprint', 'Y');
