Create Gateway API plugin

[JuniorJPDJ]

Gateway API is better approach than Ingress, but it's still in beta.
Would be cool to see official support inside vcluster, but plugin is imo better idea now as it's in beta.

https://gateway-api.sigs.k8s.io/

Also cert-manager plugin support for gateway api would be cool too as cert-manager can create certificates for gateway api resources.

@JuniorJPDJ thanks for creating this issue! Makes sense, we'll check if we can create either a plugin or integrate this even into vcluster core

Is there any progress/roadmap on this? We would also be interested in this feature. Also curious if contributions are welcomed, if we have time we may be able to gave a hand.
