Requesting Shared Images

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`.
