Allure Reports are much more readable than standard Behat/Fastest outpout, but they are currently lacking some data that makes it easier to analyse failures.

We need to add:
1) Browser screenshots after failure
2) Browser logs
3) Application logs
as attachments.

We need to keep the existing logs/screenshots in place, because Allure Reports are not available to people outside of our organization (and we need to encourage contributions, not make them harder).
