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.

Sudarsan Reddy 7f487c2651 TUN-6775: Add middleware.Handler verification to ProxyHTTP
ProxyHTTP now processes middleware Handler before executing the request.
A chain of handlers is now executed and appropriate response status
codes are sent.

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.

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).

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.
