+brief: Wazuh manager handles agent groups.
+        If a group is deleted from a master cluster, there will be an instance where the agents require a
+        resynchronization (syncreq).
+        If the group is deleted from a worker cluster, the cluster master will take care of reestablishing the
+        group structure without the need for resynchronization.
+        This test suite tests the correct functioning of the mentioned use case.
