Non-Node.js HTTP adapter does not emit 'end' for http.ClientRequest

[whitlockjc]

A user recently reported that req.on('end', function () { would not be ran when using Trireme and a non-Node.js HTTP adapter like the Netty one that is a part of this project. Here is the original report:

That thread also has a workaround but it would be nice if Trireme's non-Node.js HTTP adapters worked like Node.js itself does in this respect.
