This changes fixes a bug where cloudflared was not propagating errors
when proxying the body of an HTTP request.
In a situation where we already sent HTTP status code, the eyeball would
see the request as sucessfully when in fact it wasn't.
To solve this, we need to guarantee that we produce HTTP RST_STREAM
frames.
This change was applied to both http2 and quic transports.
ProxyHTTP now processes middleware Handler before executing the request.
A chain of handlers is now executed and appropriate response status
codes are sent.
For WARP routing the defaults for these new settings are 5 seconds for connect timeout and 30 seconds for keep-alive timeout. These values can be configured either remotely or locally. Local config lives under "warp-routing" section in config.yaml.
For websocket-based proxy, the defaults come from originConfig settings (either global or per-service) and use the same defaults as HTTP proxying.
The buffer size was big to support a compression feature that we don't
use anymore.
As such, we can now reduce this and be more efficient with memory usage.
