    I started to add some NiFi integration tests which are presently lacking, but realized
that it would be better to have that as part of a different jira.

> Nifi source is not stoppable right now. To make it stoppable, is must implement {{StoppableFunction}}.
Implementing method {{stop()}} must ensure, that the source stops receiving new messages from
Nifi and issues a final checkpoint. Afterwards, {{run()}} must return.
> When implementing this, keep in mind, that the gathered checkpoint might later be used
as a savepoint.
