Host not found when coredns used

[vilyansky]

In callisto-nginx-65f9c5c9bf-5plk2 logs:

2020/08/11 15:13:24 [emerg] 1#1: host not found in resolver "kube-dns.kube-system.svc.cluster.local" in /etc/nginx/conf.d/callisto-nginx.conf:17 nginx: [emerg] host not found in resolver "kube-dns.kube-system.svc.cluster.local" in /etc/nginx/conf.d/callisto-nginx.conf:17 When coredns used in cluster.

In this case I suggest to parametrize reslover in nginx.conf and get it value outside to values.yaml
