I have instantiated an authorised azure.mgmt.containerinstance.ContainerInstanceManagementClient object. When i iterate over .container_groups.list() I see the 3 container groups but their instance_view property is None. However, when I call .container_groups.get() the object I get has all the properties populated and I can see the instance_view property.

Therefore, unless this is somehow deliberate behaviour of list/list_by_resource_group, i.e. to return a partial resource, this is a bug.
