  1. Fail fast at startup for invalid WAN merge policy (hazelcast#18875)

    Modifications:
    - Validate wan and split-brain merge policies at node-engine creation time to fail-fast at node start time.
    - Print a warning log at execution phase of MergeOperation to catch unreasonable merge-policy 
    configs that cannot be catch at start-up time. Example to this is, you have WAN replication between 
    2 clusters, even though source cluster has per-entry-stats enabled, target cluster doesn't have it 
    enabled. In this case, MergeOperation catches this anomaly and prints it as a warning.
