Putting it all together - Developing a customer registration microservice example

So far, the examples we have seen are not more than just a simple hello world. Putting our learnings together, this section demonstrates an end-to-end customer profile microservice implementation. The customer profile microservices will demonstrate the interaction between different microservices. It will also demonstrate microservices with business logic and primitive data stores.
