Change in ovirt-engine[ovirt-engine-4.1]: core: add support for more than one virtio scsi controller

Tal Nisan has submitted this change and it was merged. Change subject: core: add support for more than one virtio scsi controller ...................................................................... core: add support for more than one virtio scsi controller Since every IO Thread has to have it's own virtio scsi controller and the current code supported only one controller, this patch adds the support for having more than one. If the num of io threads of a VM is lowered, the controller Id is re-generated for this disks. If the num of io threads is enlarged, the existing disks which already have addresses are not re-generated, only for the new disks will be assigned to new controller. Therefore, in order to enforce the rearrangement of the disks to io threads which has already been given some address, the disks have to be de-activated and activated again. The reason is to not to touch the assignement of the disks to controllers since it influences the disk arrangement inside of the guest.
