Continue to implement #2698: - Add `core/base-service/index.js` (but hold off on moving the things it imports) - Add shortcuts in `services/index.js` for Base*Service, errors, and deprecatedService. This file will be streamlined later to avoid cluttering it with rarely used bits. - Apply consistent ordering of imports and use of `module.exports` in testers. - Remove some renaming of imports. - Remove obsolete tests here and there.
