Delete Topic use-case
This use-case describes what happens when a topic is created on the Event Management component.
When a new topic is created the component will create two new roles: topicName.publisher & topicName.Subscriber
An Operator could remove the privileges for components so that they no longer can publish Events
An Operator could remove the privileges for components for them to receive Events
The enableEventPublishing Operator should react on Topic removal (and privilege changes?)
The enableEventSubscription Operator should react on Topic removal (and privilege changes?)
