IKEv1 ConfigMode: Added TRANSACTION exchange type. Added attribute_payload (IKEv2 equiv cp_payload) and data_attribute (IKEv2 equiv configuration_attribute) payload types. Did not combine with IKEv2 because it wasn't trivial to do so. This might be a task worth investigating in the future, because there is a decent amount of shared code here.
