Sudarsan Reddy 368066a966 TUN-3615: added support to proxy tcp streams 
added ingress.DefaultStreamHandler and a basic test for tcp stream proxy
moved websocket.Stream to ingress
cloudflared no longer picks tcpstream host from header

cthuang e2262085e5 TUN-3617: Separate service from client, and implement different client for http vs. tcp origins 
- 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

Adam Chalmers a278753bbf TUN-3902: Add jitter to backoffhandler 
Jitter is important to avoid every cloudflared in the world trying to
reconnect at t=1, 2, 4, etc. That could overwhelm the backend. But
if each cloudflared randomly waits for up to 2, then up to 4, then up
to 8 etc, then the retries get spread out evenly across time.

On average, wait times should be the same (e.g. instead of waiting for
exactly 1 second, cloudflared will wait betweeen 0 and 2 seconds).

This is the "Full Jitter" algorithm from https://aws.amazon.com/blogs/architecture/exponential-backoff-and-jitter/

Igor Postelnik 0b16a473da TUN-3869: Improve reliability of graceful shutdown. 
- Don't rely on edge to close connection on graceful shutdown in h2mux, start muxer shutdown from cloudflared.
- Don't retry failed connections after graceful shutdown has started.
- After graceful shutdown channel is closed we stop waiting for retry timer and don't try to restart tunnel loop.
- Use readonly channel for graceful shutdown in functions that only consume the signal

Igor Postelnik a945518404 TUN-3811: Better error reporting on http2 connection termination. Registration errors from control loop are now propagated out of the connection server code.
