pytest-CleanSlate: work around test state pollution

About

pytest-cleanslate is a small plugin for the pytest test framework which, as the name implies, helps give each test module a "clean slate" to execute. Plugins such as pytest-forked and pytest-isolate allow you to execute tests in separate processes, working around in-memory test "state pollution" resulting from their execution, but do not protect against pollution caused by top-level code in test modules. This is what pytest-CleanSlate remedies.
