> This test should check the rebalance on persistent caches in two scenarios:
>  # Full rebalance which triggered by two event types: node join and node left the topology (need to enable baseline auto-adjust and setting the small baseline auto-adjust timeout).
>  # Historical rebalance which triggered by joining to cluster of missed node with existing PDS:
>  ** Build the cluster with persistence enabled and preload data to it.
>  ** Stop one node without baseline change.
>  ** Make new data updates.
>  ** Return leaved node to the cluster.
> The both tests 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: rebalance statistics.
