Upgrade to Synnefo v0.15.1

This release has no notable upgrade steps.

Select Pithos storage backend

Starting with version 0.15.1, we introduce the ability to select or change the storage backend for the Pithos Service between NFS and RADOS. In order to use RADOS, you should first install snf-image>=0.15 to all Ganeti nodes. For more information about selecting the Pithos storage backend see Pithos storage backend.

This is the first version that allows running the whole Synnefo stack over RADOS only.
