Add logging about not using async for Sequential and Parallel runners

[merelcht]

Description

Closes #2405

Development notes

Added logging message only to SequentialRunner and ParallelRunner because async mode can't be used with ThreadRunner. Added tests to check the message is shown/not shown when expected.

@merelcht , thank you for this PR,
I noticed a little bit of code repetition in 2 classes, maybe we need to consider to move this common code to AbstractRunner class, like:

if isinstance(self, (SequentialRunner, ParallelRunner)) and not self._is_async:
            self._logger.info(...

It's a good point, but then I was thinking the AbstractRunner ideally shouldn't have any logic specific to the implementations, so that's why I did it on the individual classes.

you right, it's ambiguous trade-off, we can leave it as it is 👍
