Looks like this: https://screenshot.googleplex.com/LxhOHojQMdA.png

The implementation is almost copy-pasta of
https://github.com/luci/luci-go/blob/master/tokenserver/appengine/impl/delega...

Most of the reusable code is already concentrated in tokensigning.Inspector{...}
thing. The rest needs concrete proto types, and thus can't be deduplicated.
