     [ https://issues.apache.org/jira/browse/IGNITE-16109?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kirill Gusakov updated IGNITE-16109:
------------------------------------
    Description: 
For handle rebalance feature safe and correct we need to add the following listeners on the start of new Raft node:
- {{onLeaderChanged()}} - must be executed from the new leader when raft group changes the leader.
- {{onChangePeersError(errorContext)}} - must be executed when any errors during changePeers occurred
- {{onChangePeersCommitted(peers)}} - must be executed with the list of new peers when changePeers has successfully done.

- {{onChangePeersCommitted(peers)}} - must be executed with the list of new peers when changePeers has successfully done.

Also, maybe we will need additional listener method
- {{onStableUpdate(peers)}}, which must be invoked together with applying configuration (oldQuorum, newQuorum) -> (newQuorum)
