Mirza Aliev updated IGNITE-27725:
---------------------------------
    Description: 
h3. Motivation

We would like to add some logs to Placement Driver and around, so we could 
properly catch rare case when Placement Driver wasn't registered after 
metastorage leader re-election. 

* We have added logs to the most suspicious place -- 
{{LogicalTopologyEventListener#onTopologyLeap}}. This method wasn't even 
implemented, meaning that if some node is lagging in terms of CMG raft group, 
and rejoins after some time, it won't receive 
{{LogicalTopologyEventListener#onNodeJoined}}, hence all login with node 
subscription will be missed. The first step is to log the place and it must be 
fixed as soon as possible https://issues.apache.org/jira/browse/IGNITE-27770
* Proper logging of {{LeaseTracker}} start and stop
* Starting Ragt client in {{PlacementDriverManager}}, receiving leader change 
event.
etc.
