Introduce job completed event

The VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event will be triggered once a job
(such as migration) finishes and it will contain statistics for the job
as one would get by calling virDomainGetJobStats. Thanks to this event
it is now possible to get statistics of a completed migration of a
transient domain on the source host.
