Subject: [PATCH 16/26] iotests: Add more "skip_if_unsupported" statements to
 the python tests

O-Subject: [RHEL-AV-8.2.1 qemu-kvm PATCH v2 01/11] iotests: Add more "skip_if_unsupported" statements to the python tests
Bugzilla: 1778593
RH-Acked-by: Eric Blake <eblake@redhat.com>

From: Thomas Huth <thuth@redhat.com>

The python code already contains a possibility to skip tests if the
corresponding driver is not available in the qemu binary - use it
in more spots to avoid that the tests are failing if the driver has
been disabled.

While we're at it, we can now also remove some of the old checks that
were using iotests.supports_quorum() - and which were apparently not
working as expected since the tests aborted instead of being skipped
when "quorum" was missing in the QEMU binary.
