Leverage spring-cloud-cloudfoundry-service-broker for broker controllers

[gberche-orange]

Currently, the open-service-broker does not leverage the spring-cloud-cloudfoundry-service-broker for broker controllers (only for unit tests).

open-service-broker/server/src/main/groovy/com/swisscom/cf/broker/controller/BindingController.groovy

Line 39 in 9aefbbf

@RequestMapping(value = '/v2/service_instances/{service_instance}/service_bindings/{id}', method = RequestMethod.PUT)

This implies a higher maintenance/effort and a feature coverage, especially as the OSB API evolves in time.

Thanks @gberche-orange , you're absolutely right and we have it in our plan to get rid of standard osbapi controllers on our codebase.
