TUN-8441: Correct UDP total sessions metric to a counter and add new ICMP metrics
...
cloudflared_udp_total_sessions was incorrectly a gauge when it
represents the total since the cloudflared process started and will
only ever increase.
Additionally adds new ICMP metrics for requests and replies.

TUN-7477: Decrement UDP sessions on shutdown

need to be cleared and the metric needs to be decremented.

TUN-7477: Add UDP/TCP session metrics
...
New gauge metrics are exposed in the prometheus endpoint to
capture the current and total TCP and UDP sessions that
cloudflared has proxied.

TUN-7227: Migrate to devincarr/quic-go
...
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.

TUN-5600: Close QUIC transports as soon as possible while respecting graceful shutdown
...
This does a few fixes to make sure that the QUICConnection returns from
Serve when the context is cancelled.
QUIC transport now behaves like other transports: closes as soon as there
is no traffic, or at most by grace-period. Note that we do not wait for
UDP traffic since that's connectionless by design.
