cyclades: Fix issue with storing images

'version' parameters.  Otherwise, any change of the image (e.g.
location) would cause the creation of a new image which would result in

..to Archipelago, as 'origin_size' parameter.

Currently, the volume object is annotated with the size of the origin,
but this information is not stored in DB. This will have to be changed
when Synnefo supports detachable volumes.
cyclades: Fix wrong import
pithos: Improve test

Extend test for listing objects until a specific timestamp
