This brings oodviewer into k0.
oodviewer started as a py2/flask script running on q3k's personal infra,
which is now being turned down.
This is a rewrite of that script into similarly mediocre Go, conforming
to the exact same mediocre JSON API and spartan HTML interface.
This also deploys it into k0 in the oodviewer-prod namespace. It's
already running, but the 'oodviewer.q3k.me' TTL has to expire before it
begins handling traffic.
