--------------------------------------

             Summary: Initialize message factory provider for extensions
                 Key: IGNITE-28667
                 URL: https://issues.apache.org/jira/browse/IGNITE-28667
             Project: Ignite
          Issue Type: Task
            Reporter: Ilya Shishkov
            Assignee: Ilya Shishkov
             Fix For: 2.19


{{DiscoveryDataBag}} for joining node data:
# Stores it in {{#joiningNodeData}} map of type {{Map<Integer, Serializable>}}
# Uses {{JoiningNodeDiscoveryData#joiningNodeData}} with return type {{Serializable}} to provide it to Ignite components.

*For the RU purposes:*
# {{Serializable}} should be replaced by {{Message}} for joining node data in {{DiscoveryDataBag}},  {{DiscoveryDataPacket}} and corresponing Ignite components.
# Corresponding data classes should implement {{Message}} as much as possible. Eg., {{NodeEncryptionKeys}}, {{GroupKeyEncrypted}} can be easely refactored to become messages.
# For generic objects like consistent id, node attributes extra message wrapper can be used, eg.:
{code}
public class ObjectData implements MarshallableMessage {
    private Serializable data;

    @Order(0)
    byte[] dataBytes;

    ...
}
{code}
