Add a hypervisor configuration to specify if IO should
be handled in a separate thread. Add support for iothreads for
virtio-scsi for now. Since we attach all scsi drives to the
same scsi controller, all the drives will be handled in a separate
IO thread which would still give better performance.
Going forward we need to assess if adding more controllers and
attaching iothreasds to each of them with distributing drives
among teh scsi controllers should be done, based on more performance
analysis.
