incubator/oauth-proxy Allow path to be configured (#2936)

* incubator/oauth-proxy Allow path to be configured

Allow path to be configured on the ingress. If one has a vhost that
needs to be shared with oauth proxy, then we need to be able to proxy
pass just /oauth2 to the proxy. Thus allowing it to be configured here.

* Update Chart version

* Fix variable inside range loop.
