support for path based routing

[martin2176]

I wanted to use this helm chart to demo path based routing in ingress controller.
Is it possible to add a a variable which would publish the app under a different root other than /.
I have the annotation in ingress nginx.ingress.kubernetes.io/rewrite-target: /
I did an http trace in browser to find what is going on.
