feat(argo-cd): add loadBalancerClass field for Service resource

Most users of ArgoCD may use `Ingress` (and soon `HTTPRoute`), but for those who may want to use `Service` of type `LoadBalancer`, this would be useful.
The `loadBalancerClass` field would allow for a `CloudProvider` agnostic way of offloading the reconciliation for Kubernetes Service resources of type `LoadBalancer` to an external controller.
