mgr/balancer: add per pool concurrent optimization limit

the main point is that in general we have physical isolated storage
pools in our products, so the cluster-wide target_max_misplaced_ratio
option would not make much sense in such case.
Introducing a fine-grained alternate throttling mechanism instead make
things much better now!
