Add a custom timeout for log replica test
Add a custom timeout for log replica test. Let's keep these outliers to a minimum.
Hmm, it's really slow - clocked `1m16.735s` on my machine. 

Let me see first if it can be made faster.<|||||>It's like 4 tests in one - so it adds up - I guess I could just split it in several sub-tests.<|||||>What do you guys prefer here? We can also make it @slow - which will shave off ~80sec - it doesn't need to run all the time at all.<|||||>No strong opinion on my side, do what you think is best!<|||||>oh, but these are multi-gpu tests so they are @slow already as they only run on our machine only

@LysandreJik, does this impact the push workflow? or just scheduled one?

If so I'd also `@slow` all the fairscale/apex tests, as these definitely don't need to run often at all.<|||||>Here we go: https://github.com/huggingface/transformers/pull/12710 - reworked 1 to 4 subtests, shouldn't run longer than the timeout now.<|||||>merged the alternative solution, closing this then<|||||>The multi GPU tests are run every time there is a commit on `master`, so it's not only slow tests. We have fast and slow GPU & multi-GPU tests.

Thanks a lot for splitting that test, way better solution.<|||||>ok, so should we put fairscale and apex tests to @slow then? These are hardly ever used by anyone, so would be a waste to spend $$ and time on those.<|||||>We can, but it's not a super high priority, they seem to run quickly enough
