Support labels configuration in EnvoyProxy spec

[jukie]

Description:
I'd like the ability to configure labels on the envoyService spec within the EnvoyProxy resource so that I can do things like target a specific cilium IP pool.

Would it be accepted if I made this change in KubernetesServiceSpec?

gateway/api/v1alpha1/shared_types.go

Line 258 in d1cc0ba

type KubernetesServiceSpec struct {

Any extra documentation required to understand the issue.

@jukie see https://github.com/kubernetes-sigs/gateway-api/blob/main/apis/v1/gateway_types.go#L722 it might be that these are supported already using Gateway crd

I may be doing something wrong but labels added there are not applied to the service backing the gateway. I was doing something wrong, this does work!

But that also wouldn't allow for more granular labels that should only be applied to the service.

sounds like a valid use case, assigning this to you @jukie, thanks !
