The patch looks good to me

> After Kubernetes-based agents were enabled on TC, unit test builds started to
> fail with OOM errors. After having inspected the heap dump, we've discovered
> that Kubernetes agents report to have 64 cores in their processors. Since the
> number of cores influences the number of threads the Raft component creates,
> we ended up with having more than 500 Raft-related threads, which consumed
> all available memory.
> As a quick solution to this problem, I propose to reduce the number of
> threads used by the Raft component, at least in tests.
