Remove includeAuthorization parameter for GET services

[KevLoh]

As agreed in BCF Hackathon 2018 p2, we should remove the additional includeAuthorization parameter in GET services (https://github.com/BuildingSMART/BCF-API#428-determining-allowed-topic-modifications).

Always return authorization, topic_status etc..

@ykulbak @jasollien could you guys give a bit of feedback if it would be easy to do from the server side? Easy meaning, it's not going to slow down all requests when we always include the authorization information.

[GeorgDangl]

We got feedback from Oracle and Catenda that this should not be a problem, meaning we can always include the authorization parameters in responses and simplify the API.

Agreed in todays telecon to do this change in the hackathon
