Once we have a way for Sherrifs to backfill all PGO tests for a certain build, we need to tweak SETA to consider all PGO jobs as low-value.

As per https://bugzilla.mozilla.org/show_bug.cgi?id=1274310#c42 we would probably use SETA's preseed.json concept to force all PGO related jobs into the low value state.

I am thinking the preseed.json: https://github.com/mozilla/ouija/blob/master/src/preseed.json here we would hack for a wild card: {"platform": "linux64", "buildtype": "opt", "name": "*", "expires": "", "action": "coalesce"}, then when we parse preseed.json in failures.py: https://github.com/mozilla/ouija/blob/master/tools/failures.py#L255 we would then detect a * (or ALL, or '') value for the "name" and adjust the list accordingly. This shouldn't be too hard- it is just making sure we don't mess up buildbot when it uses SETA.

this is implemented and deployed as of today
