Ngninx template for Openshift

Create a full deployment for an Nginx Proxy that reads its configuration from a config map.

The config map can be edited online and only requires a rolling deployment to take effect.

Quickstart:

oc new-app -f https://gist.githubusercontent.com/ksingh7/f6ca0c13cb9902fe96463704d27065af/raw/da5e0cf24f63de0a5b94b0497d5036e9e2f7b1f5/nginx-template.yaml -p NAME="my-proxy"
