Migrate Lambda to use servlet core (#1650)

- It updates to the latest milestones
- It deletes CDK module (it will be moved to starter). 
- It moves away from [AWS Serverless Java Container](https://github.com/awslabs/aws-serverless-java-container). It use servlet core. 
- It supports both payload versions v1 and v2.
- Handlers use standard [AWS Lambda Java Events](https://github.com/aws/aws-lambda-java-libs/tree/main/aws-lambda-java-events) POJOs.
- TCK passes almost complety. 
- There is some work still to do in the the proxy-test. Several tests don't pass.
