Please document or provide schema for CloudEvent that is sent to Camel integrations.
Specifically the metadata part.

For example the metadata that is sent out form props: https://github.com/RedHatInsights/notifications-backend/blob/1ba71ad87685daaec558520517d05a9118e756ff/backend/helpers/create_application_full.py#L55-L62
And then used here as an example here: https://github.com/RedHatInsights/notifications-backend/blob/1ba71ad87685daaec558520517d05a9118e756ff/camel-sender-demo/src/main/java/com/redhat/cloud/notifications/demoCamelSender/Main.java#L88

Based on conversation with pilhuhn we know that the url in metadata/props is mandatory and there is no value validation.

Thank you.
