This is a minimally functioning version of the service that supports deploying both as an API GW+Lambda or as a Docker image.
Reorganized the code such that the Lambda and Docker can feed off the same CfnNagService object and in turn map the requests/responses as is appropriate for the particular medium. As you make commits, strive to ensure that design stays true to avoid duplication.
There is support for digital signatures.
There is no support for rule updates.
There is no support for ECS (deployment templates or the like).
There is no support for authentication in GW or private endpoints.
There are a lot of other "doesn't do X"that I won't enumerate here - but will generate issues for them.
