As expected by Peter in [1], the hardcoded 3 seconds for waiting the
RAID array to rebuild are not enough on slow test host runners. This
test already failed at least once for that reason, in [2].
In order to fix those failures, this commit adds extra logic to allow
several attempts, before failing. The timeout is currently set at 10
attempts, waiting 3 seconds between each attempts. To help even more,
those 3 seconds are also scaled with the timeout_multiplier.
