The existing OpenStack operator will only work for Python 2.7 Airflow Containers and will fail to function properly for Airflow Containers running on Python 3.x This update will fix the problems with the environment variables. The current assumption is that the shipyard.conf will contain the required information for the OpenStack environment and it will be consumed by Airflow Dag to execute the OpenStack commands. This will likely change in future when DeckHand is ready for integration as the required information will be retrieved from DeckHand instead The xcom portion has been removed as it does not really serve any purpose at the moment. It might get added back in future depending on the needs. Change-Id: I0c5fb56462fdbc43a20897373118f510cbb2e01c
