+Type: []string
+Default: []string{}
+Description: The server groups this server is in. Group hopping and default server
+selection accept server groups on top of regular server names,
+randomly choosing one of its servers. If a server name and a group name
+are in conflict, the server name is preferred.
+This feature can be used to implement simple load balancing.
