Support 'reason' argument to pytest.fail

[charliermarsh]

Summary

Per the API reference, reason was added in version 7, and is equivalent to msg (but preferred going forward).

I also grepped for msg usages in flake8_pytest_style, but found no others (apart from those that reference unittest APIs.)

Closes #3387.
