Adjust the replica rebalance calculating ordering to avoid static order. (#535) * Adjust the replica rebalance calculating ordering to avoid static order. The problem of a static order is that the same set of replicas will always be the ones that are moved or state transited during the rebalance. This randomize won't change the algorithm's performance. But it will help the Helix to eliminate very unstable partitions.
