Create basic sample application

[Albertoimpl]

When creating your first service broker, there is a lot of knowledge and tricks that you have to be aware of.
Even though we simplify a lot of that boilerplate with this project, there are still a lot of tiny details that may not be trivial if you are implementing a service broker for the first time.
It would be great to have a sample application, with maybe a blog post that walks through everything to ease the usage of this project to people who never created a service broker before.

more confusion creates with 2 terminologies : Spring Cloud App Broker and Spring Cloud Open Service Broker .So please consider this as well.
