Devin Carr ea6fe121f8 TUN-7167: Respect protocol overrides with --token
Previously, if run with both `--protocol` and `--token` the protocol
would be incorrectly overridden to QUIC.

Devin Carr 0f95f8bae5 TUN-6938: Force h2mux protocol to http2 for named tunnels
Going forward, the only protocols supported will be QUIC and HTTP2,
defaulting to QUIC for "auto". Selecting h2mux protocol will be forcibly
upgraded to http2 internally.

João Oliveirinha 513855df5c TUN-7073: Fix propagating of bad stream request from origin to downstream
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.

Sudarsan Reddy 9339bb9485 TUN-6929: Use same protocol for other connections as first one
This PR changes protocol initialization of the other N connections to be
the same as the one we know the initial tunnel connected with. This is
so we homogenize connections and not lead to some connections being
QUIC-able and the others not.

There's also an improvement to the connection registered log so we know
what protocol every individual connection connected with from the
cloudflared side.

João Oliveirinha 20ed7557f9 TUN-6679: Allow client side of quic request to close body
In a previous commit, we fixed a bug where the client roundtrip code
could close the request body, which in fact would be the quic.Stream,
thus closing the write-side.
The way that was fixed, prevented the client roundtrip code from closing
also read-side (the body).

This fixes that, by allowing close to only close the read side, which
will guarantee that any subsquent will fail with an error or EOF it
occurred before the close.

Sudarsan Reddy 99f39225f1 TUN-6617: Dont fallback to http2 if QUIC conn was successful.
cloudflared falls back aggressively to HTTP/2 protocol if a connection
attempt with QUIC failed. This was done to ensure that machines with UDP
egress disabled did not stop clients from connecting to the cloudlfare
edge. This PR improves on that experience by having cloudflared remember
if a QUIC connection was successful which implies UDP egress works. In
this case, cloudflared does not fallback to HTTP/2 and keeps trying to
connect to the edge with QUIC.

João Oliveirinha 4016334efc TUN-6642: Fix unexpected close of quic stream triggered by upstream origin close
This commit guarantees that stream is only closed once the are finished
handling the stream. Without it, we were seeing closes being triggered
by the code that proxies to the origin, which was resulting in failures
to actually send downstream the status code of the proxy request to the
eyeball.

This was then subsequently triggering unexpected retries to cloudflared
in situations such as cloudflared being unable to reach the origin.

Devin Carr b849def673 TUN-6460: Rename metric label location to edge_location
For Google's managed prometheus, it seems they reserved certain
labels for their internal service regions/locations. This causes
customers to run into issues using our metrics since our
metric: `cloudflared_tunnel_server_locations` has a `location`
label. Renaming this to `edge_location` should unblock the
conflict and usage.
