Refactor Examples folder and scripts

- Move scripts to Examples
- Add a common config.sh script
- Move SAM templates to Examples/scripts/SAM
- Move Serverless templates to Examples/scripts/serverless
- Update the scripts to work with new folder structure and config.sh
- Move Dockerfile to Examples
