Fixes up some abstraction so that we can add other jobs backends and
specs, migrations, etc will work as expected.
Also remove some unused parameters from the Delayed::Job methods for
finding and locking jobs.
test plan: run the database migrations on a new db, and migrations
should work without error. delayed jobs should also be created and
processed by workers without error.

To simplify the queries done on jobs:
* failed jobs now go in a separate table
* jobs that go past their max_run_time don't immediately get re-run.
instead a periodic job goes through every 5 minutes and unlocks
expired jobs
* strand performance is much improved
* we filter out jobs that can't be run because of strand
restrictions completely in the database query now
* better indexes help with these queries and the sub-select
