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.
