Have Housekeeper run workers in a deterministic order

[sgoggins]

Is your feature request related to a problem? If so, please describe the problem: Currently, Augur runs all the workers with switch=1 when it starts. Logically, in order to optimize the contributor data, and minimize duplicate contributors (as a possibility), workers should run in the following order:

1. Facade
2. GitHub (Issues), GitLab Issues Worker, Linux Badging Worker, Dependencies Worker (in parallel)
3. Pull Request Worker, GitLab Merge Request Worker, Release Worker, Value Worker (in parallel)
4. Repo_Info Worker, Insight Worker
5. Message Insights Worker
6. Clustering Worker
7. Discourse Analysis Worker
8. Pull Request Analysis Worker
9. Contributor Worker
10. Contributor Breadth Worker
