To-Do

0.2

set up a CI
Rework the different APIs
- Find out what the user can modify, and what is reserved to the internals (like synthetics, lastUpdated, ...)
- Which messages can be set
- Which external REST based APIs are supported~~~~

Think about integrated support for information like (unit/content-type, source timestamp, ...)
Make KafkaSource generic, align with Notifier trait
Think about handling "by application" limitation.
Allow a way to modify the thing, overriding a non-empty outbox
- Allow more fine-grained control over this
Implement WASM
Prevent cyclic events
Finer grained RBAC
