Make GenericTrafficGen class abstract
GenericTrafficGen class is now an abstract class. Only optional methods are implemented. - 'run_traffic' and 'terminate' are mandatory. - 'listen_traffic', 'verify_traffic' and 'wait_for_instance' are optional. By default these methods doesn't execute any action.
