Overloads Kafka queue while simultaneously introducing a consumer side delay leading to a lag spike The result of that featureflag can be observed with numerous metrics in grafana (e.g. kafka_consumer_lag_avg)
also adjusted the resource limit for the frauddetection service since it kept dying

Changes
This PR adds a new feature flag
kafkaQueueProblemsto the opentelemetry demo. Upon activating the feature flag, the producer (checkoutservice) overloads Kafka by sending 100 extra messages to the queue per actual order. Simultaneously, the consumer (frauddetectionservice) delays the claiming of the messages by 1 second per message. This leads to a sudden spike in consumer lag. This is an interesting, real world observability scenario because it simulates queue problems in kafka which afaik no feature flag does yet. Metrics that monitor consumer lag can be viewed in Grafana (e.g.kafka_consumer_lag_avg).Also increased the resource limitations of the frauddetection service since it kept dying due to resource exhaustion. This also happened without my modifications to the service.
Looking forward to your feedback!
