configmap for helmingresscontroller must have proxy-protocol set to true

[chkp-mnichols]

When attempting to deploy the helm chart in eks, nginx will not properly pass traffic because
proxy-protocol in the configmap is commented out.

A separate helm chart will be created for eks in a future commit. In the meantime, you can edit the configmap.yaml, uncomment the proxy-protocol statement, repackage the helm chart and it will work.
