Ordered output of parallel test run

[Januson]

Description

A configuration option that would enable ordered logging of parallel tests.

Additional information

Currently when the tests run in parallel the output is mixed randomly according to how the tests run. Which makes sense since it's outputting the result as soon as the test finishes. This makes output harder to read. Especially in case of parameterized tests.

There are cases where I don't really care about the immediate output. For example when tests run on CI. It would be nice if where was an option to make the test output ordered. Even at the price of it not being immediate. It could hold on until the whole test class finishes and output the result of its tests organized as serial themes do.
