Comment 29 for bug 1604879

Note for QA:
The patch should been tested in several storage backend configurations. The required minimum is:
1. No Ceph backend at all https://pageshot.net/images/f20bf975-95be-467c-9dc4-87fd200f6060.png
2. Ceph backend for Glance only https://pageshot.net/images/3cf13747-2abe-4576-a250-1ceccb6ffe71.png
3. Ceph backend for Glance and Ceph RadosGW for objects https://pageshot.net/images/65252a5d-a5e2-46c7-bae2-1ab73c51d7a4.png
4. Swift for Glance and Ceph RadosGW for objects https://pageshot.net/images/65cd5324-b0cb-4989-8680-daf3041152cb.png

In all cases object storage should be deployed correctly and it's should be possible to create containers, upload objects to them, etc.
