[libvirt] [PATCH 2/3] vz: add virStorageFileFormat to connection structure

[Mikhail Feoktistov]

Virtuozzo6 supports only ploop disks for containers and virtual machines.
Virtuozzo7 supports only qcow2 for virtual machines.
In this patch we add virStorageFileFormat variables to connection structure.
Each variable contains disk format that we support for virtual machines and containers.
In openConnection() callback we get virtuozzo version
and select proper virStorageFileFormat values.
