There is a way to get the version of the API being used. We need such
feature to work correct with different versions of the Cinder API
from third-party tools.

This change adds a new admin-api to allow admin to fetch
specified backend capabilities which includes volume stats and

Fixing the import of volume_transfers in v2 client.
It was importing volume_transfers from v1.
Even though at this moment the imported files are identical, in the
future volume_transfers in v2 may change, and v2 client should use the
v2 volume_transfers.
Since the intent is for v1 to be deprecated in the future, we must be
careful with these little details.
