Refactor docker_base to use inversion of control

[lathanh]

Pull Request Description

Use inversion of control in docker_base so that it can more strongly and easily ensure consistency between various implementations (GCP implementation to come).

This also includes teasing apart the several batch prep steps (weather, assets, and jobs) into their own methods so they can each be more easily understood, shared, and maintained.

I still would like to see these PRs getting entries in the changelog, so we can track when these things go in.

Sure; done!
