text search of historical job logs

[davepacheco]

When running into a new CI failure, when I suspect the failure to be unrelated to the change being tested, I often want to know "have we hit this particular failure on main before?" or "have we ever hit this particular failure before"? I usually search GitHub issues first for some uncommon part of the failure message. That helps sometimes. It would be neat if I could similarly search past buildomat job logs, too. A regex seems handy but really I'm usually just picking an exact string match (filename of a panic, or a panic message, etc).
