Refactor this sample (or add a parallel repository) to both simplify the example and introduce new features that are now generally available.

• Simplify to use non-zipped actions (which were needed for the MySQL client package) and use Cloudant as the data store
• Update to use a combination of API Gateway + Web Actions.
• Provide a linkage to an alternate approach with the Serverless Framework.
• Support a wskdeploy manifest to replace deploy.sh as it matures.
• Incorporate cost/performance metrics against existing ways to provide serverful web APIs.
• Include a linkage to the why behind this approach.
