We've been getting reports of lots of gray (i.e. missing) thumbnails on the desktop NTP. We should (re-)introduce metrics to track the number of impressions with local, remote, and missing thumbnails.
We now have metrics! Note that they only distinguish "thumbnail" vs "failed (gray) thumbnail"; we can't tell apart local thumbnails from remote (Kodachrome) ones in client metrics. If we need that, we'll have to use server-side metrics.
