Change subject: core: Update QCOW volumes in 4.0 DC to the default QCOW version. ...................................................................... core: Update QCOW volumes in 4.0 DC to the default QCOW version. After upgrade of oVirt 4.1 if there were any added disks in a 4.0 DC those disks will not be initiailzed with the default QCOW version since the update could be done only if VDSM reported the QCOW version of the new volume which was only introduced in 4.1 DCs. Therefore any added QCOW volumes in DC 4.0 should be initialized with the default QCOW version which is 0.10. Also added an upgrade script that updates all the QCOW volumes that were added to a 4.0 DC after the oVirt upgrade, to the default QCOW version.
