Retrieve cached idealMappings for all Rebalancers instead of recomputing it
during every rebalance round.
Retrieve cached idealMappings for all Rebalancers (AutoRebalancer,
DelayedRebalancer and CustomRebalancer) for any rebalance strategies. This will
avoid recompute idealmapping (preference list) if there is no
idealstate/instanceconfig/LiveInstances changes.
