All header transformation code from h2mux has been consolidated in the connection package since it's used by both h2mux and http2 logic.
Exported headers used by proxying between edge and cloudflared so then can be shared by tunnel service on the edge.
Moved access-related headers to corresponding packages that have the code that sets/uses these headers.
Removed tunnel hostname tracking from h2mux since it wasn't used by anything. We will continue to set the tunnel hostname header from the edge for backward compatibilty, but it's no longer used by cloudflared.
Move bastion-related logic into carrier package, untangled dependencies between carrier, origin, and websocket packages.
- 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
