Demo scenario: Product Recommendation component

[dhmlau]

Description / Steps to reproduce / Feature proposal

As part of the e-commerce store demo scenario in #1476, this task is to create the Product Recommendation component. Information will be fetched from a SOAP/REST service.

Questions:

• Do we want SOAP service instead of REST service?
  • Use REST for now, SOAP can be a different branch / service at a later date. The main concept to show off is the Service Proxy integration / Usage.

Acceptance Criteria

• Controller using service proxy to talk to Product Recommendation REST API
• Mockup of Product Recommendation Service (Express / LoopBack App / Serverless Function).

I don't have a strong opinion on whether the operation(s) depend on SOAP service(s) or REST API, but if the other components are using REST, then we might want to use SOAP for diversity.

Let's start with REST and add SOAP if necessary.
