Describe Stream topics

It seems that people are interested to have an exhaustive list of Stream topics and the related capabilities.

And ideally provide a scenario for each topic to validate that the topic is being used.

It could be a subpage of https://doc.nuxeo.com/nxdoc/nuxeo-stream/

The list of topics is requested for an environment where Kafka is shared among several applications and these applications don't have the permission to directly create topics.
