epriestley 19b2c3d3d0 Formalize configuration sources and source stacks
Summary: Currently, we have a configuration stack for unit tests, but they're built in to `PhabricatorEnv`. Pull them out and formalize them, so we can add more configuration sources (e.g., database).

Test Plan: Ran unit tests, web requests, scripts. This code had fairly good existing test coverage.
