Router should be accept proxy protocol on port 1936

[jkroepke]

I'm using on the AWS the new NLB for loadbalancing the router.

AWS supports the proxy protocol days ago. I configure the IP:1936/healthz as healthcheck.

If the target group of the loadbalancer has active proxy protocol, the healthcheck are fired with proxy protocol, too. Since the port 1936 is handeld by the openshift-router process, it must be accept the proxy protocol to response valid answers for the loadbalancer.

Version

oc version

oc v3.7.0+7ed6862
kubernetes v1.7.6+a08f5eeb62
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server
openshift v3.7.0+7ed6862
kubernetes v1.7.6+a08f5eeb62

Steps To Reproduce

1. Setup a multiple Openshift Routers with active PROXY_PROTOCOL support.
2. In AWS, setup a network loadbalancer, a target group (use ip as target instead instances!), define the healthcheck to HTTP:1936/healthz and enable the proxy protocol

Current Result

After some minutes, the health status will be unhealthy

Expected Result

All Target should be healthy
