[Qemu-devel] [PATCH v6 04/11] tests: refactor python I/O tests helper main method

["Daniel P. Berrange" <berrange@redhat.com>]

The iotests.py helper provides a main() method for running
tests via the python unit test framework. Not all tests
will want to use this, so refactor it to split the testing
of compatible formats and platforms into separate helper
methods
