OOM in chaos testing scenario:
*Chaos configuration:*
* Kill a random pod in the cluster.
* Wait until the pod is ready, node joins physical and logical topology.
* Take a pause for 3 minutes.
* Repeat from step #1.
*Steps to reproduce:*
* Start the replication from a huge amount of data
* Start the chaos script that will work for the whole duration of replication.
* Monitor the number of records in the tables.
Heapdump shows that the problem is in the
{{PartitionReplicaListener#txCleanupReadyFutures}} map that holds ~600 mb in
several {{PartitionReplicaListener}}.
