Developing a comprehensive microservice example

So far, the examples we have considered are no more than just a simple "Hello world." Putting together what we have learned, this section demonstrates an end-to-end Customer Profile microservice implementation. The Customer Profile microservices will demonstrate interaction between different microservices. It also demonstrates microservices with business logic and primitive data stores.
