Title: Add pithos backend version check

Synnefo version 0.15.1 has introduced a selectable storage backend
resulting necessary changes to ModularBackend class.
In order to keep back-compatibility with older synnefo versions
we check pithos backend version and instantiate ModularBackend
class appropriately.
