John Griffith 6d70d6adf9 Implement new attach Cinder flow
This change integrates support of the Cinder 3.44
volume attachment API.

The patch bumps the compute service version to
check whether all the compute nodes are upgraded to the
version that can handle attach and detach with the new
flow.

To enable the new flow we also need the 3.44 or higher
microversion from Cinder. We check that in the API and
if it's not available we fall back to the old
attach/detach flow.
