ingress-nginx 0.16.2 (https://github.com/kubernetes/ingress-nginx/releases/tag/nginx-0.16.2) This patch simplify ingress-nginx deployment by default deploy on master, with customizable options; on the other hand, remove the additional Ansible group "kube-ingress" and its k8s node label injection. Reference to https://kubernetes.io/docs/concepts/services-networking/ingress/#prerequisites: GCE/Google Kubernetes Engine deploys an ingress controller on the master. By changing `ingress_nginx_nodeselector` plus custom k8s node label, user could customize the DaemonSet deployment target. If `ingress_nginx_nodeselector` is empty, will deploy DaemonSet on every k8s node.
