      Give a sync replica cache with 3 nodes
      Introduce a network partition
      Change the cache value
      Fix the network partition
      Check the new cache value

      https://github.com/diegolovison/jgroups-chaos
      mvn test -Dtest=InfinispanPartitionHandlingTest -Dlog4j.configurationFile=log4j2-ispn-conflict-manager.xml

      config:

               cacheConfigurationBuilder.clustering().cacheMode(CacheMode.REPL_SYNC)
            .partitionHandling().mergePolicy(MergePolicy.REMOVE_ALL);

      logs:

      15:44:31,827 INFO  (stateTransferExecutor-thread--p22-t1) [CLUSTER] [Context=org.infinispan.CONFIG] ISPN100002: Starting rebalance with members [Diegos-MacBook-Pro-40446, Diegos-MacBook-Pro-6797, Diegos-MacBook-Pro-52614], phase READ_OLD_WRITE_ALL, topology id 14
15:44:56,725 TRACE (stateTransferExecutor-thread--p22-t1) [StateReceiverImpl] Cache fooCache attempting to receive replicas for segment 83 from [Diegos-MacBook-Pro-40446, Diegos-MacBook-Pro-6797, Diegos-MacBook-Pro-52614] with topologyId=12, timeout=215112

      expected result: for one key, running all cluster in the same machine. I think that we can improve the business rules to avoid taking more than 10 seconds to finish the test.
