Expose original conn variable to client

[PassTheMayo]

It would be very helpful if you could add the original conn to the RethinkDB client? It would allow people to assign their own events to it, including the close event.

Hum, I think there's a misunderstanding on how connections are used.

Connections are created/reused/closed as needed, there's a pool of connections, not a single one. There's also no need to listen to a specific connection. The driver already takes care of that.
