add support for the Service Catalog to the model

[jstrachan]

relates to fabric8io/fabric8-maven-plugin#1050 but it'd be good to have a jar for the service catalog YAML resources so that we can use them with kubernetes-client / fabric8-maven-plugin

Need to add following API resources.

• ClusterServiceBroker(List and Object)
• ServiceClass(List and Object)
• ServiceInstance(List and Object)
• ServiceBinding(List and Object)

@iocanel shall we add this to kubernetes client?

considering https://github.com/snowdrop/service-catalog-java-api.

What I'd personally want is a single project that will ship individual modules for the following:

• kubernetes-model
• kubernetes-client
• openshift-model
• openshift-client
• istio-model
• istio-client
• servicecatalog-model
• servicecatalog-client

So that we can release everything in a single step, but without having too coarse grained modules.

So to answer the question, I'd say let's start by merging the kubernetes-model with kubernetes-client as a first step and then let's gradually bring the rest of the stuff in.
