DevTools FE uploader: create checker instance to validate uploads
Runs on a separate GCE instance from the uploader and periodically checks
that earlier commits have been uploaded to the devtools frontend appspot instance.
This runs a simple HTTP server in a separate daemon thread so GCP/Stackdriver
can do a periodic uptime check. Ideally, because the HTTP server and checker thread
run in the same process, they should have similar uptime.
