Ingress resources point to an IngressClass that does not exist

[pratik705]

Describe the bug
During the installation of ingress-controllers, we override the ingress class to nginx and nginx-cluster[1]. But, I can see there are few ingress resources which points to nginx-openstack ingressclass which doesnt exist[2].

[1]

# kubectl get ingressclass
NAME            CONTROLLER             PARAMETERS   AGE
nginx           k8s.io/nginx-ingress   <none>       3d19h
nginx-cluster   k8s.io/nginx-ingress   <none>       3d19h

[2]

openstack       cinder-cluster-fqdn                    nginx-openstack   cinder.dfw-ospcv2-staging.ohthree.com                                                                                               80, 443   3d17h
# kubectl get ing -A |egrep -i nginx-openstack |wc -l

To Reproduce
