Please Support net-gateway-api

[kahirokunn]

Currently there is no entry for gateway-api in IngressConfigs. It would be great if you could support net-gateway-api when it graduates from the sandbox!

@kahirokunn Could you be more specific regarding this feature? Like is it just a new option to configure the knative serving to use gateway api? OR is it a replacement of how we currently configure the ingress? There are tons of ingresses that support gateway api, how can we configure each of them as the ingress of knative serving?

I am considering this one first.

I don't think it is necessary to consider which Ingress supports the Gateway API. We believe it is sufficient to support the provision of HTTPRoute and gRPCRoute in the format supported by the standard Gateway API. It is better for users to build their own Ingress that supports the Gateway API. By the way, I would like to integrate cilium's Gateway API.

1. allow config-gateway configuration
2. install net-gateway-api This is all that is required. I don't think we need to provide the details for each vendor. For example, in the case of Cilium, it is as follows.
