ceph_volume_client: add versioning

Browse Source 
Add class attributes to CephFSVolumeClient to version
its capabilities.

'version' attribute stores the current version number
of CephFSVolumeClient.

'compat_version' attribute stores the earliest version
number of CephFSVolumeClient that the current version is
compatible with.
