Subject: [PATCH 18/26] iotests/055: refactor compressed backup to vmdk

O-Subject: [RHEL-AV-8.2.1 qemu-kvm PATCH v2 03/11] iotests/055: refactor compressed backup to vmdk
Bugzilla: 1778593
RH-Acked-by: Eric Blake <eblake@redhat.com>

From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>

Instead of looping in each test, let's better refactor vmdk target case
as a subclass.
