[PATCH v15 5/7] iotests: test the zoned format feature for qcow2 file

[Niklas Cassel <cassel@kernel.org>]

From: Sam Li <faithilikerun@gmail.com>

The zoned format feature can be tested by:
$ tests/qemu-iotests/check -qcow2 zoned-qcow2

Changes by Niklas Cassel:
- drop the zone append size limit from the image the test creates
- test, on a second image with zone resource limits, that each zone
  error is reported with its own errno, and the zone resource
  management of writes, OPEN ZONE and FINISH ZONE
- test that a zoned image needs version 3 and zones of whole clusters,
  and that resetting a zone leaves the data of the other zones alone
- test that a closed zone that a write fills no longer counts as an
  active zone
- list the test in the qcow2 section of MAINTAINERS
