Hi, I was trying to find if its possible to create custom plugins without dropping them into `$AIRFLOW_HOME/plugins` (or the directory defined in `airflow.cfg`). We can define one location in `airflow.cfg` but I have multiple projects which will have their own workflows so, ideally I would want to implement custom plugins (along with operators, sensors, etc.) in those repositories itself and let them get discovered from there. Checking through documentation and browsing code I concluded that the only way to get this done is by ensuring that `$PYTHONPATH` is set to include directories where these custom modules are stored.
So, I want to ask if there is a better way to handle this? If not, can `plugins_manager` (AirflowPlugin) be improved to suit this use-case? Kind Regards, Ritesh
