Use custom ports

[pichouk]

For a specific use case, I need my Nginx ingress controller to listen on different ports than 80/443.

I cannot map my specific hosts ports (here 40080 and 40443) to ingress controller 80/443 ports because hostPort parameter is not working for now (see kubernetes/kubeadm#11 and kubernetes/kubernetes#31307 ). So I have no other choices than to map my container ports to my node ports (hostNetwork: True).

So, I tried to modify Nginx to use custom HTTP/S ports based on a configmap.
I work on a specific local branch and I already made some modifications.

But I'm stuck with some lua stuff. It appears that HTTP/S ports are hardcoded in rootfs/etc/nginx/lua/vendor/lua-resty-http/lib/resty/http.lua file. I don't know anything about lua so I am sure how to use custom ports in that part.
I can make a string substitution in this file at the Ingress controller startup, but not sure if it is the right way to do...

If anyone can help on this. Also interesting on feedback about this feature, maybe it is a too specific case.

This will be covered when #620 is fixed.
