title: AWS MWAA (Managed Apache Airflow) where to put the python code used in the dags?
body: <p>Where do you put your actual code? The dags must be thin, this assumes that when the task starts to run it would do the imports, and run some python code.</p>
  <p>When we were on the standalone airflow I could add to the PYTHON_PATH my project root and do the imports from there, but in the AWS managed airflow I don't find any clues.</p>
