[libvirt] [PATCH v4 3/4] qemu: block: store the delete flag in libvirtd's status XML

Since blockcommit is asynchronous, libvirtd can be restarted while the operation runs. To ensure the information necessary to finish up the job is not lost, serialisation to and deserialisation from the status XML is added. To unittest this, the new element was only added to the active commit test, the non-active commit test doesn't have the new element so as to test its absence.
