feat: Add parameter and jobs database schema (#81)

* feat: Add parameter and jobs database schema

This modifies a prior migration which is typically forbidden,
but because we're pre-production deployment I felt grouping
would be helpful to future contributors.

This adds database functions that are required for the provisioner
daemon and job queue logic.

* Add comment to acquire provisioner job query

* PostgreSQL hates running in parallel
