pithcat: Add support for Archipelago images

Synnefo version 0.16.0 completely removes the selectable storage backend

necessary changes to the ModularBackend class.
In order to keep backward compatibility with older Synnefo versions, we
check the Pithos backend version and instantiate the ModularBackend
class appropriately.
