What this PR does / why we need it

Adds conformance reports for Apache APISIX Ingress Controller 2.2.0, the first release of this project to implement Gateway API v1.6.0, and lists it under Conformant implementations.

Two reports, one per deployment mode. The controller drives one shared APISIX data plane rather than provisioning one per Gateway, and configures it either through the APISIX Admin API against etcd (default) or by pushing the whole configuration to an etcd-less APISIX (apisix-standalone, what APISIX calls its API-driven mode). Both modes run the same suite.

Nothing fails in either report.

The skips are listed with their reasons in the README and in test/conformance/conformance_test.go upstream. Four TLSRoute tests pin mode: Passthrough, which APISIX does not do because it terminates TLS and matches stream routes by SNI. HTTPRouteMultipleGateways wants a route served independently from each parent, which one shared data plane does not do. The rest are gaps tracked for follow-up.

The reports come from the APISIX Conformance Test workflow run on the 2.2.0 tag, which pulls the published 2.2.0 images, and are submitted exactly as produced. The README's Reproduce section runs the same steps by hand.

Which issue(s) this PR fixes

None.

Does this PR introduce a user-facing change?

NONE

Two reports for 2.2.0, one per deployment mode: the controller drives one
shared APISIX data plane, configured either through the Admin API against etcd
(default) or pushed in full to an etcd-less APISIX (apisix-standalone).

GATEWAY-GRPC passes core and extended with nothing skipped. GATEWAY-HTTP and
GATEWAY-TLS are partial, and the skips are listed with their reasons in the
README.

Hi @AlinsRan. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

if this implementation is not passing the most basic TLSRoute test, what is it passing? I think it would be better to not claim GATEWAY-TLS support in this case

I understand where you are coming from with the TLSRoute skips, but at the moment, doing TLS passthrough with TLSRoute is considered Core conformance for that object; if you don't support TLS passthrough with TLSRoute, it's not correct to say you support TLSRoute.

To be honest, we never even considered that an implementation would not support passthrough, because in most cases it's easier to implement than TLS termination.

I'm very curious as to why APISIX chooses not to implement TLS passthrough. Perhaps you could explain that a bit?

However, I don't think we can accept the conformance report as it currently stands, because, as I said, Passthrough support is considered Core for TLSRoute.
