Incorrect Cattle Public Endpoint Annotation

[ghost]

Rancher versions: rancher/rancher: v2.1.0

Steps to Reproduce:

1. Deploy rancher v2.1.0
2. Edit Restricted Pod Security Policy

Host Network: Yes: The use of host networking
Allowed Capabilities: NET_BIND_SERVICE
Host Ports Policy: range 8080 - 8080, 8443 - 8443

3. Deploy custom cluster using restricted Pod Security Policy from above
4. Edit yaml for cluster > system > nginx-ingress-controller

containers:
   - args:
      - /nginx-ingress-controller
      - --default-backend-service=$(POD_NAMESPACE)/default-http-backend
      - --configmap=$(POD_NAMESPACE)/nginx-configuration
      - --tcp-services-configmap=$(POD_NAMESPACE)/tcp-services
      - --udp-services-configmap=$(POD_NAMESPACE)/udp-services
      - --annotations-prefix=nginx.ingress.kubernetes.io
      - --http-port=8080
      - --https-port=8443

ports:
  - containerPort: 8080
     hostPort: 8080
     name: http
     protocol: TCP
  - containerPort: 8443
     hostPort: 8443
     name: https
     protocol: TCP

5. Redeploy nginx-ingress-controller
6. Deploy workload and add ingress rule (.xip.io)

Results: The ingress rule that is created uses port 80 for public endpoints. The ingress rule will not work since the ingress controller is listening on port 8080 and 8443.
