Radosgw swift cli create container ACL failed

[Jorge Sorondo]

Detailed bug description:
 When in the controller shell swift command line is unable to add ACLs to containers (using CEPH Hammer backend)
Steps to reproduce:
 Created container through openstack cli with:
openstack container create marvel-art
attempted to add swift ACL with:
swift post -r ".r:*,.rlistings" marvel.art
No changes were made:
openstack container show marvel-art

| container | marvel-art |
| object_count | 1 |
+--------------+------------+
swift stat -v marvel-art

If I go through horizon though and make the container public then display the stats or container on the cli it shows this:

openstack container show marvel-art

| account | v1 |

                      Account: v1
                    Container: marvel-art

                     Read ACL: .r:*
                    Write ACL:

but if I try to add another ACL via the swift command line it deletes the existing ACL and displays no ACL output.
Expected results:
 It should list the correct ACLs
Actual result:
 ACLs are not listed and attempting to add ACL after making the container public in horizon deletes the public access ACL.
Reproducibility:
 100%
Workaround:
 Haven't found a work around beyond making the container public on horizon
Impact:
 low
