Ilya Shishkov updated IGNITE-28793:
-----------------------------------
    Description: 
Following DTO implements {{Serializable}}:
# {{BaselineStateAndHistoryData}}

They are transferred in {{DiscoveryDataBag}} ({{DiscoveryDataPacket}}) and 
should be transfromed to a {{Message}}. 

Some important tips:
# Implementation of {{Serializable}} should be removed if possible. (If not 
stored somewhere in MetaStorage, or in PDS).
# If it is difficult to transform to {{Message}}, message-clone DTO can be 
added, eg. {{QueryIndexMessage}}.
# Keep in mind {{#writeObject}} / {{#readObject}} and {{#readExternal}} / 
{{#writeExternal}} methods, if any.
