Description

There are some evidence, that rebalancing huge cache without rebalance throttling can cause OOM on supplier. We need to cover this scenario.

Scenario:
1. Start two nodes and 1 replicated cache with data region much more than heap.
2. Stop one of the node.
3. Load data to cache almost equal to size of data region.
4. Start node.

Goal is to run experiments with parameters
1. Heap size
2. Cache size
3. Rebalance batch size.
4. Rebalance throttle
