    ignite-4154 Optimize amount of data stored in discovery history
    Discovery history optimizations:
    - remove discarded message for discovery pending messages
    - remove duplicated data from TcpDiscoveryNodeAddedMessage.oldNodesDiscoData
    - do not store unnecessary data in discovery EnsuredMessageHistory
    - use special property for EnsuredMessageHistory size instead of 
IGNITE_DISCOVERY_HISTORY_SIZE
    Affinity history optimizations:
    - do not store calculated primary/backup maps in history
    - try save the same assignments instance for caches with similar affinity
    Exchange messages optimizations:
    - do not send duplicated partition state maps for caches with similar 
affinity
    - use zip compression for data sent in exchange messages

>          Issue Type: Bug
>    Affects Versions: 2.1
>            Reporter: Yakov Zhdanov
>            Assignee: Ilya Kasnacheev
>
> There was a GC pause on client that caused servers to drop client due to 
> inability to establish TCP communication connection. Then it took some time 
> for client to detect that it has been dropped. During that time client many 
> times attempted to connect to server which can be seen in the logs. After 
> client detected its drop and reconnected servers fired node added event and 
> no log flood can be found any more.
> We need to find out why client was reconnecting via communication and did not 
> detect the drop for such a long time.
> I hope this can be reproduced in test:
> * start 2 servers
> * start client
> * suspend all client threads with Thread.suspend() - just filter threads of 
> current JVM by name and suspend ones belonging to the client.
