> This test should check the rebalance on in-memory caches in basic scenario: rebalance triggered by two event types: node join and node left the topology.
> The test should be able to run on large amounts of data enough to ensure rebalancing time about of several minutes.
> Test parameters:
> # Initial node count (derived from test context);
> # Cache count - the count of caches to create and data preload;
> # Cache entry count - the count of entries per cache to preload;
> # Cache entry size - the size of each cache entry in bytes;
> # Rebalance thread pool size - the value for {{IgniteConfiguration#rebalanceThreadPoolSize}} property (see [configuring rebalance thread pool title|https://ignite.apache.org/docs/latest/data-rebalancing#configuring-rebalance-thread-pool]), expected that greater value makes rebalance faster.
> # Rebalance batch size - the value for {{IgniteConfiguration#rebalanceBatchSize}} property (see [other rebalance properties|https://ignite.apache.org/docs/latest/data-rebalancing#other-properties]), expected that greater value makes rebalance faster on large data or [throttling|https://ignite.apache.org/docs/latest/data-rebalancing#throttling] enabled (rebalanceThrottling > 0).
> # Rebalance throttle - the value for {{IgniteConfiguration#rebalanceThrottle}} property (see [rebalance message throttling|https://ignite.apache.org/docs/latest/data-rebalancing#throttling], [other rebalance properties|https://ignite.apache.org/docs/latest/data-rebalancing#other-properties]), 0 - throttling disabled, greater value makes rebalance slower.
> Test result: time taken to rebalance process.
