Devin Carr 5aaab967a3 TUN-7477: Decrement UDP sessions on shutdown
When a tunnel connection is going down, any active UDP sessions
need to be cleared and the metric needs to be decremented.

Devin Carr 8a3eade6d3 TUN-7553: Add flag to enable management diagnostic services
With the new flag --management-diagnostics (an opt-in flag)
cloudflared's will be able to report additional diagnostic information
over the management.argotunnel.com request path.
Additions include the /metrics prometheus endpoint; which is already
bound to a local port via --metrics.
/debug/pprof/(goroutine|heap) are also provided to allow for remotely
retrieving heap information from a running cloudflared connector.

Sudarsan Reddy 39847a70f2 TUN-7558: Flush on Writes for StreamBasedOriginProxy
In the streambased origin proxy flow (example ssh over access), there is
a chance when we do not flush on http.ResponseWriter writes. This PR
guarantees that the response writer passed to proxy stream has a flusher
embedded after writes. This means we write much more often back to the
ResponseWriter and are not waiting. Note, this is only something we do
when proxyHTTP-ing to a StreamBasedOriginProxy because we do not want to
have situations where we are not sending information that is needed by
the other side (eyeball).

Devin Carr 2b4815a9f5 TUN-7543: Add --debug-stream flag to cloudflared access ssh
Allows for debugging the payloads that are sent in client mode to
the ssh server. Required to be run with --log-directory to capture
logging output. Additionally has maximum limit that is provided with
the flag that will only capture the first N number of reads plus
writes through the WebSocket stream. These reads/writes are not directly
captured at the packet boundary so some reconstruction from the
log messages will be required.

Added User-Agent for all out-going cloudflared access
tcp requests in client mode.
Added check to not run terminal logging in cloudflared access tcp
client mode to not obstruct the stdin and stdout.

Sudarsan Reddy 1abd22ef0a TUN-7480: Added a timeout for unregisterUDP.
I deliberately kept this as an unregistertimeout because that was the
intent. In the future we could change this to a UDPConnConfig if we want
to pass multiple values here.

The idea of this PR is simply to add a configurable unregister UDP
timeout.

The lucas-clemente/quic-go package moved namespaces and our branch
went stale, this new fork provides support for the new quic-go repo
and applies the max datagram frame size change.

Until the max datagram frame size support gets upstreamed into quic-go,
this can be used to unblock go 1.20 support as the old
lucas-clemente/quic-go will not get go 1.20 support.

with the new remote configuration when sent as it does a check against

Devin Carr 38cd455e4d TUN-7373: Streaming logs override for same actor
To help accommodate web browser interactions with websockets, when a
streaming logs session is requested for the same actor while already
serving a session for that user in a separate request, the original
request will be closed and the new request start streaming logs
instead. This should help with rogue sessions holding on for too long
with no client on the other side (before idle timeout or connection
close).

tunnel that a user could provide to give custom names to their
connectors.

James Royal 171d4ac77c AUTH-3122 Verify that Access tokens are still valid in curl command
Before this change, the only sure fire way to make sure you had a valid
Access token was to run `cloudflared access login <your domain>`. That
was because that command would actually make a preflight request to ensure
that the edge considered that token valid. The most common reasons a token
was no longer valid was expiration and revocation. Expiration is easy to
check client side, but revocation can only be checked at the edge.

This change adds the same flow that cfd access login did to the curl command.
It will preflight the request with the token and ensure that the edge thinks
its valid before making the real request.

Sudarsan Reddy 5e212a6bf3 TUN-7360: Add Get Host Details handler in management service
With the management tunnels work, we allow calls to our edge service
   using an access JWT provided by Tunnelstore. Given a connector ID,
   this request is then proxied to the appropriate Cloudflare Tunnel.

   This PR takes advantage of this flow and adds a new host_details
   endpoint. Calls to this endpoint will result in cloudflared gathering
   some details about the host: hostname (os.hostname()) and ip address
   (localAddr in a dial).

   Note that the mini spec lists 4 alternatives and this picks alternative
   3 because:

   1. Ease of implementation: This is quick and non-intrusive to any of our
      code path. We expect to change how connection tracking works and
      regardless of the direction we take, it may be easy to keep, morph
      or throw this away.

   2. The cloudflared part of this round trip takes some time with a
      hostname call and a dial. But note that this is off the critical path
      and not an API that will be exercised often.

Devin Carr b89c092c1b TUN-7134: Acquire token for cloudflared tail
cloudflared tail will now fetch the management token from by making

cloudflared login).

Refactored some of the credentials code into it's own package as
to allow for easier use between subcommands outside of
`cloudflared tunnel`.

Sudarsan Reddy 5dbf76a7aa TUN-7335: Fix cloudflared update not working in windows
This PR fixes some long standing bugs in the windows update
paths. We previously did not surface the errors at all leading to
this function failing silently.

This PR:

1. Now returns the ExitError if the bat run for update fails.
2. Fixes the errors surfaced by that return:
    a. The batch file doesnt play well with spaces. This is fixed by
    using PROGRA~1/2 which are aliases windows uses.
    b. The existing script also seemed to be irregular about where batch
    files were put and looked for. This is also fixed in this script.
