chore(framework): Initial commit (#8221)

**What**
- Initiate the framework package (which is just a place to move things around for now)
- move the config loader and related resources as well as the `ConfigModule` type
- Create a ConfigManager singleton which prepare and store the config (later can be stored entirely in the container) and allow for easier test override
- re export the logger from the framework
- replace medusa config loader with the framework one
- `build` run type check on tests as well but `prepublishOnly` will not fail on build if tests are typed broken
