Add app behind hangar.concourse-ci.org

This is an nginx server that does a redirect to a zoom room used by the team for meetings like: standup, retro, everyone is wfh because covid-19 You may wonder: why do the redirect with an html page? You can do HTTP 301 redirect with just nginx redirect rules. and you would be correct! But then other people's opinions get pushed onto you and you have to do hacky things to get around it. tldr: the ingress comes with a health checker that is not smart. See kubernetes/ingress-gce#42 for more details. Longer answer: The ingress used by GKE setups a health check that ONLY hits '/' against your pod. Because my initial nginx.conf just did 301 redirects this healthcheck was forever failing because it would never get HTTP 200. I tried to get around this by having nginx listen on another port for health checking and always return HTTP 200 on that port. I then had to expose both ports to the ingress controller. The ingress controller decided to healthcheck BOTH ports that were exposed on the container and send all traffic to port 9000 where it was getting the HTTP 200's. At this point I threw my hands up and wrote some HTML to do the redirect for me. Signed-off-by: Taylor Silva <tsilva@pivotal.io>
