Cartridge's properties should be available under
org.apache.stratos.messaging.domain.topology.Service's properties. If not
it's a bug :-)

ServiceCreatedEvent generated when you deploy a new Cartridge.
org.apache.stratos.messaging.event.topology.ServiceCreatedEvent.ServiceCreatedEvent(String,
ServiceType)
|_org.apache.stratos.cloud.controller.topology.TopologyEventPublisher.sendServiceCreateEvent(List<Cartridge>)
