move (non-api) clients (inc redis) from app/__init__.py to extensions when clients are defined in app/__init__.py, it increases the chance of cyclical imports. By moving module level client singletons out to a separate extensions file, we stop cyclical imports, but keep the same code flow - the clients are still initialised in `create_app` in `__init__.py`. The redis client in particular is no longer separate - previously redis was set up on the `NotifyAdminAPIClient` base class, but now there's one singleton in `app.extensions`. This was done so that we can access redis from outside of the existing clients. 2019-02-14 14:25:31 +00:00			`from notifications_utils.clients.antivirus.antivirus_client import (`
