What's wrong?

Description:

We need to document all NATS events we have going around in our system to ensure we do not create collisions, or miss crucial events.

Documentation example:

Events should be described as follows:

## TOPIC/EVENT: <topicname>/<eventname>
<Describe the purpose of the event>
### Consuming Services:
- <list each consuming service>
### Producing Services:
- <list each producting service>
  - <any events that could trigger this event>
### Payload Description:
<details><summary>Click to expand</summary>
<paste json example>
</details>

Acceptance Criteria:

• NATS events are documented in file messages-documentation/wstack/eventList.md in https://gitlab.eclipse.org/eclipse/xfsc/libraries/messaging/cloudeventprovider repository
• All events used at the time of work on this issue must be documented according to the example above.
