Run AWS Lambda tests locally

[antonpirker]

For testing our AWS Lambda integration in CI we used to create actual Lambda functions and run them in actual AWS.

This PR changes this and uses AWS SAM for running a AWS Lambda like environment in a Docker container. In this local AWS Lambda we create the Lambda functions that our tests invoke.

Fixes #2795
