qemu: Report VIR_DOMAIN_JOB_OPERATION

Browse Source 
Not all async jobs are visible via virDomainGetJobStats (either they are
too fast or getting the stats is not allowed during the job), but
forcing all of them to advertise the operation is easier than hunting
the jobs for which fetching statistics is allowed. And we won't need to
think about this when we add support for getting stats for more jobs.
