Fix pfioh hello with Openshift route
Fix pfioh hello with Openshift route

The pfioh hello command would return a bad gateway error with the openshift route
due to the fact the pfioh would not send a 200 response code back.
Added that into pfioh.py and now we can get a response with the openshift route.
