 Review comment:
   @Clarkkkkk Thanks for your review! Please see also my first comment.
   `TaskTest` is a test based on legacy code, would be ported to FLIP-6 
codebase soon as a sub task of FLINK-10392. All changes under `TaskTest` is 
temporary. Once the porting job done and if this PR doesn't get merged, I would 
do a rebase.

>  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}}.
