João "Pisco" Fernandes 76badfa01b TUN-8236: Add write timeout to quic and tcp connections
## Summary
To prevent bad eyeballs and severs to be able to exhaust the quic
control flows we are adding the possibility of having a timeout
for a write operation to be acknowledged. This will prevent hanging
connections from exhausting the quic control flows, creating a DDoS.

Joel May 2baea15387 ZTC-234: Replace ICMP funnels when ingress connection changes
Origintunneld has been observed to continue sending reply packets to the first incoming connection it received, even if a newer connection is observed to be sending the requests.

OTD uses the funnel library from cloudflared, which is why the changes are here.

In theory, cloudflared has the same type of bug where a ping session switching between quic connections will continue sending replies to the first connection.  This bug has not been tested or confirmed though, but this PR will fix if it exists.

Remove send and return methods from Funnel interface. Users of Funnel can provide their own send and return methods without wrapper to comply with the interface.
Move packet router to ingress package to avoid circular dependency

Sudarsan Reddy 7f487c2651 TUN-6775: Add middleware.Handler verification to ProxyHTTP

Sudarsan Reddy 9bb7628fbc TUN-6772: Add a JWT Validator as an ingress verifier
This adds a new verifier interface that can be attached to ingress.Rule.
This would act as a middleware layer that gets executed at the start of
proxy.ProxyHTTP.

A jwt validator implementation for this verifier is also provided. The
validator downloads the public key from the access teams endpoint and
uses it to verify the JWT sent to cloudflared with the audtag (clientID)
information provided in the config.

Sudarsan Reddy eb36716ba4 TUN-6774: Validate OriginRequest.Access to add Ingress.Middleware
We take advantage of the JWTValidator middleware and attach it to an
ingress rule based on Access configurations. We attach the Validator
directly to the ingress rules because we want to take advantage of
caching and token revert/handling that comes with go-oidc.
