Add support to loadBalancerClass on nginx service

Describe the solution you'd like
We use Antrea as our CNI, and we need to include the field loadbalancerClass: antrea in our services of type loadbalance.

Can you include it in helm templates/controller-service.yaml

Service Sample:

apiVersion: v1
kind: Service
metadata:
  name: nginx-ingress
  annotations:
    service.antrea.io/external-ip-pool: "myexternalpool"
spec:
  externalTrafficPolicy: Local
  type: LoadBalancer
  loadBalancerIP: 192.168.0.1
  loadBalancerClass: antrea

This can be achieved in this block here:

templates/controller-service.yaml

  {{- if .Values.controller.service.loadBalancerClass }}
  loadBalancerClass: {{ .Values.controller.service.loadBalancerClass }}
  {{- end }}

values.schema.json also should be changed:

            "loadBalancerClass": {
              "default": "",
              "title": "The loadBalancerClass",
              "$ref": "https://raw.githubusercontent.com/nginxinc/kubernetes-json-schema/master/v1.33.1/_definitions.json#/definitions/io.k8s.api.core.v1.ServiceSpec/properties/loadBalancerClass"
            },

Hi @rodrigosandrin thanks for reporting!

Be sure to check out the docs and the Contributing Guidelines while you wait for a human to take a look at this 🙂

Cheers!

@rodrigosandrin You are able to provide your own Service and let the helm chart know the name of it with controller.service.name and disable autogeneration with controller.service.enable: false. We are also happy to accept a PR for the loadbalancerClass functionality.
