Document Custom Kafka Topics

[Cali0707]

What is changing? (Please include as many details as possible.)

In the Eventing Kafka Broker, we will soon support users being able to define custom topic templates for their kafka topics for Brokers and Channels.

How will this impact our users?

Users will be able to define custom topic templates for their brokers and channels when using the eventing kafka broker. However, users will need to be cautious when upgrading, and ensure that all of their Channels have been given a Status.Annotation for the kafka topic before changing the channel topic template. This is because we are not currently recording the existing topic being used on the channel, and if the template is changed before we have recorded this then the Channel will create a new topic following the new template.

In what release will this take happen (to the best of your knowledge)?
