    IGNITE-8855 Added exponential delay before reconnection that was caused by small EXCHANGE_HISTORY

> After fixing client nodes hangs in IGNITE-8657 another issue was found out: when EXCHANGE_HISTORY
is significantly smaller than number of clients they interfere with each other on initial
exchange and make reconnect attempts over and over again.
> To avoid this random delay (maybe exponential) should be added for clients before making
new reconnect attempt.
