- extracted ResponseWriter from proxyConnection
- added bastion tests over websocket
- removed HTTPResp()
- added some docstrings
- Renamed some ingress clients as proxies
- renamed instances of client to proxy in connection and origin
- Stream no longer takes a context and logger.Service
Also changed the socks test code so that it binds to localhost, so that
we don't get popups saying "would you like to allow socks.test to use
the network"
