Failed to initialize the Unity driver because it cannot connect to the Unity system.
Env:
- OpenStack version: Stein
- storops version: 0.5.12
- requests version: 2.20.0
storops uses `requests` to send rest to the Unity system. `requests` handles the possible redirect if needed.
The connection to the Unity system could be redirected to the CAS if not authorized. But due to a bug `requests` drops the auth in the headers.

And the symptom you would see about this issue is like:
>>> u = storops.UnitySystem('10.245.101.39', 'admin', 'xxxxxxxx')
>>> u.info
