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

> Issue Type: Bug
> Reporter: Sergey Chugunov
> Assignee: Ivan Bessonov
> Priority: Major
>
> 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.
