We want to see a list of images which are shared with a
given tenant. We issue a GET request to
http://glance.example.com/shared-images/tenant1.
We will get back JSON data such as the following:
{'shared_images': [
{'image_id': 1,
'can_share': false}
...]}
The `image_id` field identifies an image shared with the tenant named by member_id. If the tenant is authorized to further share the image, the `can_share` field is `true`.
