From: Peter Hoyes <Peter.Hoyes@arm.com>

pytest [1] is a test runner for Python test suites. Its advantages
over vanilla unittest are:

 * An existing tool with a familiar entry-point.
 * A flexible plugin architecture that supports a large plugin
   ecosystem, including for parallel testing and embedded testing.
 * Fixtures, for more flexible and granular sharing of setup/teardown
   logic.

This patch chain proposes introducing pytest as an alternative test
runner for the Bitbake self-tests.

pytest is mostly compatible with unittest TestCases out of the box,
but some small adaptations are included in this patch chain, alongside
a pytest.ini file and an update to the README.

This patch chain does not mandate how the pytest package is obtained,
apart from a reference to PyPI in the README. The 'minversion' is set
to 7.3, the latest version, in the pytest.ini file.
