[ovirt-devel] Merge patch "qemuimg: add support for convert progress"

[Christopher Pereira]

qemu-img operations can take very long and there is currently no way to 
see their progress.

It would be nice to include this patch to display the progress of a 
qemu-img operation (uploaded in November):
https://gerrit.ovirt.org/#/c/33910/

Canceling the qemu-img task from Engine is also something that should be 
addressed at some point.
'copyImage' tasks are displayed via vdsClient.
Is there any particular reason why a "Cancel" button was never added to 
the Engine's Task list?
