Add fluent CircuitBreaker configuration to Kafka listeners

[Ferchke7]

Adds a CircuitBreaker() method to KafkaListenerConfiguration so Kafka listeners can opt into Wolverine's standard circuit breaker policy through the fluent API.

• Example

.CircuitBreaker(cb =>
                    {
                        cb.MinimumThreshold = 10;
                        cb.PauseTime = TimeSpan.FromMinutes(1);
                    })
