Nuno Diegues 902e5beb4f TUN-6729: Fix flaky TestClosePreviousProxies
I can only reproduce the flakiness, which is the hello world still
responding when it should be shut down already, in Windows (both in
TeamCity as well as my local VM). Locally, it only happens when the
machine is under high load.

Anyway, it's valid that the proxies take some time to shut down since
they handle that via channels asynchronously with regards to the event
that updates the configuration.
Hence, nothing is wrong, as long as they eventually shut down, which the
test still verifies.

Nuno Diegues 4ac68711cd TUN-6725: Fix testProxySSEAllData
This test was failing on Windows. We did not catch it before because our
TeamCity Windows builds were ignoring failed unit tests: TUN-6727

 - the fix is implementing WriteString for mockSSERespWriter
 - reason is because cfio.Copy was calling that, and not Write method,
   thus not triggering the usage of the channel for the test to continue
 - mockSSERespWriter was providing a valid implementation of WriteString
   via ResponseRecorder, which it implements via the embedded mockHTTPRespWriter
 - it is not clear why this only happened on Windows
 - changed it to be a top-level test since it did not share any code
   with other sub-tests in the same top-level test

Devin Carr cfef0e737f TUN-6720: Remove forcibly closing connection during reconnect signal
Previously allowing the reconnect signal forcibly close the connection
caused a race condition on which error was returned by the errgroup
in the tunnel connection. Allowing the signal to return and provide
a context cancel to the connection provides a safer shutdown of the
tunnel for this test-only scenario.

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.

Sudarsan Reddy 91eba53035 TUN-6639: Validate cyclic ingress configuration
This reverts commit d4d9a43dd7.

We revert this change because the value this configuration addition
brings is small (it only stops an explicit cyclic configuration versus
not accounting for local hosts and ip based cycles amongst other things)
whilst the potential inconvenience it may cause is high (for example,
someone had a cyclic configuration as an ingress rule that they weren't
even using).

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.

Sudarsan Reddy d4d9a43dd7 TUN-6639: Validate cyclic ingress configuration
It is currently possible to set cloudflared to proxy to the hostname
that traffic is ingressing from as an origin service. This change checks
for this configuration error and prompts a change.
