jetty-httpclient-12: send method must pass along implemented response…

… listeners

The super HttpRequest.send call says:

> The listener passed to this method may implement not only Response.CompleteListener
> but also other response listener interfaces, and all the events implemented will be notified.

The current implementation passes through a lambda that implements CompleteListener only, and
does not delegate-in-scope to any other callback methods you might provide
