Fix regression with ingress.class annotation introduced in 0.9-beta.18

0.9-beta.18

Image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.9.0-beta.18

Breaking changes:

The NGINX ingress annotations contains a new prefix: nginx.ingress.kubernetes.io. This change is behind a flag to avoid breaking running deployments. To avoid breaking a running NGINX ingress controller add the flag --annotations-prefix=ingress.kubernetes.io to the nginx ingress controller deployment. There is one exception, the annotation kubernetes.io/ingress.class remains unchanged (this annotation is used in multiple ingress controllers)
