BEFORE the job runner has initiallized.
It's a GenServer because that plays REALLY nicely with the existing
Phoenix supervision tree.

Runs application startup tasks.
Any code defined here will run every time the application starts. You must
make sure that the code is idempotent and safe to run multiple times.
This is a good place to set up default settings, create initial records, stuff like that.
Should be fast - anything with the potential to be slow should be kicked off as a job instead.
