> There should be tests of rebalance for both in-memory caches and persistent caches.
>  In case of persistent caches, the tests also should check both modes of rebalance: full and historical (asserts is needed that the proper mode of rebalance was worked).
> Basic scenario:
>  Testing of rebalance triggered by two event types: node join and node left the topology (baseline change in persistent mode).
> Extended scenario:
>  Node join or left during rebalance process.
> 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.
