/**
 * This file represents how we are using Discovery.
 * 
 * The discovery configuration could either use plain UDP, or JGroups.

 * If using UDP, all the UDP properties will be filled and the jgroups properties will be
 * {@code null}.

 * If using JGroups, all the UDP properties will be -1 or {@code null} and the jgroups properties
 * will be filled.

 * If by any reason, both properties are filled, the JGroups takes precedence. That means, if
 * {@code jgroupsFile != null} then the Grouping method used will be JGroups.
