Tests that adding a very large image. We simulate the large object by setting store.large_object_size to a small number and then verify that there have been a number of calls to put_object()...

Tests that adding an image to Swift which has both an unknown size and exceeds Swift’s maximum limit of 5GB is correctly uploaded.

We avoid the overhead of creating a 5GB object for this test by temporarily setting MAX_SWIFT_OBJECT_SIZE to 1KB, and then adding an object of 5KB.
