Cool idea from deis/workflow-manager#20

As a Workflow Manager User I should:

• be able to view a simple web UI that I can reach through the kubernetes proxy
  • I should not have to authenticate to this UI
• be able to view a list of services, replication controllers and pods that are installed or running in the Deis namespace
  • so that I can quickly, at a glance, know if all the components are installed
• be able to see the versions of installed workflow components, and be notified if they are out of date
  • annotations, container images, (whatever makes sense here)
• see a large banner if deis workflow components are out of date
• poll a hosted releases API off-cluster for release information at least every 12 hours
