Description of problem:

when creating an image we can either create it under a specific tenant (using login with the admin user) or a public one. 
in the CLI we can add a specific tenant to a specific image using glance: 

root@opens-vdsb ~(keystone_admin)]# glance member-list --image-id 169243de-e5a0-4fd8-9e5c-d7af549453eb
+--------------------------------------+-----------+-----------+
| Image ID                             | Member ID | Can Share |
+--------------------------------------+-----------+-----------+
| 169243de-e5a0-4fd8-9e5c-d7af549453eb | dron      |           |
| 169243de-e5a0-4fd8-9e5c-d7af549453eb | new_ten   |           |
+--------------------------------------+-----------+-----------+
