Config assumes endpoints are http protocol

[Mirko-von-Leipzig]

Endpoints are defined as (host, port) tuples and then make the assumption that the protocol is always http.

We probably want to at least support https as well.

I can take this up with some more information about how to proceed

@varun-doshi I think the least intrusive approach would be to add an enum to the endpoint like:

enum Protocol {
    Http,
    Https,
}
