Using package_transform.sh in combination with CDK stacks

We use CDK and in order to deploy my CDK stack I need to do the following:

- cdk synth --no-staging -q
- sam build -t ./cdk.out/.template.json
- mv .aws-sam/build/template.yaml .aws-sam/build/template.yml
- Read template.yml and check if there are parameters that start with: `AssetParameters` if so remove them
- mv ./.aws-sam/build/* .
- bash adf-build/helpers/package_transform.sh --no-build

So a few questions regarding this process:

1. Does anyone how you can generate a CFN template without asset parameters? (these are added by CDK but the `sam cli` is taking this over, see: [Better together: AWS SAM and AWS CDK
](https://aws.amazon.com/blogs/compute/better-together-aws-sam-and-aws-cdk/))
1. Are there things that I might not considered?
1. Is this something we might want to support from ADF? (The `--no-build` action is needed otherwise the build happens again but then on the already build template)

Start with the listed cdk synth and sam build commands, then inspect adf-build/helpers/package_transform.sh and the generated .aws-sam/build/template.yml. Determine whether ADF should support this CDK-to-SAM workflow without rebuilding, and define the expected handling of AssetParameters and the transformed template.
