   @tillrohrmann sounds good. As you suggest, we can replace `notifyFinalState` with `updateTaskExecutionState`
since there is no different from API view and a `updateTaskExecutionState` without final state
seems wired.

with [~trohrmann@apache.org]. I start to analyze the usage of {{ActorGatewayTaskExecutionStateListener}}
and {{TaskExecutionStateListener}}.
> In conclusion, we abort {{TaskExecutionStateListener}} strategy and no any component
rely on it. Instead, we introduce {{TaskManagerActions}} to take the role for the communication
of {{Task}} with {{TaskManager}}. No one except {{TaskManager}} should directly communicate
with {{Task}}. So it can be safely remove legacy class {{TaskExecutionStateListener}}.
