Notes:
TODO(bryan-strassner): If/when the airflow plugin modules move to using
oslo config, consider using the example here:
https://github.com/att-comdev/deckhand/blob/cef3b52a104e620e88a24caf70ed2bb1297c268f/deckhand/barbican/client_wrapper.py#L53
which will load the attributes from the config more flexibly.
Keystoneauth1 also provides for a simpler solution with:
https://docs.openstack.org/keystoneauth/latest/api/keystoneauth1.loading.html
if oslo config is used.
