How to serve the /docs folder on a different port

[TedGrahamEmporia]

I want my gRPC service exposed on a different port than the DocService so I can control access to the docs via a whitelist. If I create a separate ServerBuilder than the service will be exposed on the documentation port which seems wrong. Suggestions for how to modify the below?

You can create a new virtual host which is bound to a specific port and register DocService there.
