Subject: HTTP server API changes for improved extensibility (#684)

* refactored `HttpServer` so all subclass member functions are proctected, to make it easier to extend base functionality
* added API service, can be used to enumerate registered endpoints (at `/api`). Currently only very basic information is provided
