Kashyap Chamarthy 2c94e2714c 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").
