Currently the Pomerium CLI only supports tunneling TCP connections over HTTP/1 via the CONNECT protocol. It would be nice if we could also support tunneling TCP connections over HTTP/3 (QUIC). This requires the Extended CONNECT support described in #464 , the exact details for HTTP/3 are specified in RFC9220.

We will need to detect if the server supports HTTP/3 by looking for the Alt-Svc header on the initial request. In addition the HTTP/3 connection uses the same SETTINGS_ENABLE_CONNECT_PROTOCOL setting that we will need to look for.

Go does not have an http3 client available in the standard library. However there is one available in quic-go.
