I wrote a small script that dumps the database content as a JSON. It's
reachable with https://buildd.debian.org/api/buildlogs/<pkg>

One advantage of this is that we should in theory be able to pregenerate
the content if needed - i.e. on regenerate the package's file on every
injected build log. But for now just dumping the DB should do.

I'd guess that we also want to dump all the information.

(I still need to properly commit this, but it seems to keep working
so far.)

Kind regards
