Try out ephemeral environments feature supplied by the AWS CDK Toolkit library

[dannysteenman]

AWS announced the AWS CDK Toolkit library: https://docs.aws.amazon.com/cdk/api/toolkit-lib/ which allows you to create your own workflows etc: https://community.aws/content/2wm6TNpUlPMVgcvXVySywxWaO7T/build-custom-cli-s-deployment-automation-and-more-with-the-aws-cdk-toolkit-library

One of the things it offers is the ability to setup ephermeral environments. So I want to check out if it's worth replacing the custom ephemeral environments functionality I build using projen in this repo.
