Description of problem: Currently, an uploaded QCOW2 compat level is not being verified at all when uploading it to oVirt's storage. Bug 1344289 Adds that logic, and Bug 821546 adds support to QCOW2v3. When both will be modified, We need to make sure that QCOW2v3 images can be uploaded to oVirt's storage. For doing that, we should add tests to VDSM that a verification of an uploaded image with compat level=1.1 passes if it is supported in the machine.
Already resolved as part of Bug 1344289 (https://gerrit.ovirt.org/#/c/64951/)
