feat[common]: Add support for gateway-API

[PrivatePuffin]

Is your feature request related to a problem?

Gateway-API is someday going to replace ingress.
Currently we dont support it and we, quite simply, should.

Describe the solution you'd like

We should implement all gateway API objects and ensure feature parity with ingress

Describe alternatives you've considered

.

Additional context

The nice thing about it, is that its cut into multiple objects.

• GatewayClass (cluster-wide gateway settings)
• Gateway (the entrypoint definition)
• Routes (comparable with ingress, linking entry points to svcs with domain names)

There are also some consequences of this, the most important one is that we need to "abstract" away things like hostname-fetching first.
As we cannot rely on going over all ingresses anymore to fetch hostnames, as those could also be defined on httpRoutes en tcpRoutes

Somewhat depends on: #31880
