Review comment:
Just a little reminder, using Thread.sleep() in Junit Test thread sometimes
may leads to some strange behavior. I am not sure if it is safe here.

> with [~trohrm...@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}}.
