WAN replication configuration

This is used to set up remote WAN replication between clusters, either in an active-passive or an active-active deployment. The deployment code is as follows:

<wan-replication name="our-global-cluster">
 <target-cluster group-name="paris" group-password="paris-pass">
  <replication-impl>
   com.hazelcast.impl.wan.WanNoDelayReplication
  </replication-impl>
  <end-points>
   <address>12.34.56.78:5701</address>
  </end-points>
 </target-cluster>
</wan-replication>

WanTargetClusterConfig wtcc = new WanTargetClusterConfig();
wtcc.setGroupName("paris")
 .setGroupPassword("par-pass")
 .setReplicationImplObject(new WanNoDelayReplication())
 .addEndpoint("12.34.56.78:5701");
WanReplicationConfig wrc = new WanReplicationConfig();
wrc.setName("our-global-cluster")
 .addTargetClusterConfig(wtcc);
config.addWanReplicationConfig(wrc);
