For now we have a single topic for all events. Since
we use the eventname as the key for the kafka message,
we have the property that they all get assigned to the same
parition inside kafka and therefore are in-order.

Alternatively one could have multiple topics.

The code for the kafka connection is based on:

https://github.com/confluentinc/confluent-kafka-dotnet/blob/master/examples/Web/KafkaClientHandle.cs

So far only copied details from other eventbus implementations.
Key next steps are to implement a persistent connection abstraction (class)
for the Kafka eventbus and the publish and subscribe functions. For this
we need knowledge about how Kafka works, for example how one publishes
events topics etc.
