Let's pass some additional meta information along bus connections without actually altering the communication protocol. Pass the client comm and client description string of the bus via including it in the abstract namespace client socket address we connect to. This is purely informational (and entirely user controlled), but has the benefit that servers can make use of the information if they want, but really don't have to. It works entirely transparently. This takes inspiration from how we convey similar information via credential socket connections.
