Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.5.8

Adding 2 nodes to 3 nodes ensemble with the following steps:
1. Start the new nodes (node 4, 5) and let them join the ensemble
2. Update existing nodes' configuration (node 1, 2, 3) to add the new nodes
addresses and ports
3. Rolling restart the existing nodes
4. Stop the current leader (node 2)
5. New node (node 5) becomes leader
After this, zxid in the new leader (node 5) becomes the same as the old leader
(node 2).
