Changes in this patch: - Supply 'job-id' parameter to `drive-mirror` invocation. - Issue `block-job-cancel` command on the source QEMU to gracefully complete the mirroring operation. - Stop the NBD server on the destination QEMU. - Finally, exit once the event BLOCK_JOB_COMPLETED is emitted. With the above, the test will also be (almost) in sync with the procedure outlined in the document live-block-operations.rst[+] (section: "QMP invocation for live storage migration with ``drive-mirror`` + NBD").
