Increase the traffic generator count for increased load

PETLISTADOPTIONS_CLUSTER=$(aws ecs list-clusters | jq '.clusterArns[]|select(contains("PetList"))' -r)
TRAFFICGENERATOR_SERVICE=$(aws ecs list-services --cluster $PETLISTADOPTIONS_CLUSTER | jq '.serviceArns[]|select(contains("trafficgenerator"))' -r)
aws ecs update-service --cluster $PETLISTADOPTIONS_CLUSTER --service $TRAFFICGENERATOR_SERVICE --desired-count 5
