qemu-iotests: Extend non-shared storage migration test (194)
This is the follow-up patch that was discussed[*] as part of feedback to qemu-iotest 194. Changes in this patch: - Supply 'job-id' parameter to `drive-mirror` invocation. - Once migration completes, issue QMP `block-job-cancel` command on the source QEMU to gracefully complete `drive-mirror` operation. - Once the BLOCK_JOB_COMPLETED event is emitted, stop the NBD server on the destination QEMU. - Check for both the events: MIGRATION and BLOCK_JOB_COMPLETED. 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").
