CDK app providing API Gateway endpoint to provision a CloudFormation stack. Endpoint is backed by step function that initiates the create-stack and polls (describe-stack) on an interval for completion.

This can be used as a backend to provision a AWS CloudFormation Custom Resource Type that itself is backed by a set of AWS services.
