[jira] [Created] (FLINK-11723) Remove KvState related components from NetworkEnvironment

zhijiang created FLINK-11723:
--------------------------------

             Summary: Remove KvState related components from NetworkEnvironment
                 Key: FLINK-11723
                 URL: https://issues.apache.org/jira/browse/FLINK-11723
             Project: Flink
          Issue Type: Sub-task
          Components: Network
            Reporter: zhijiang
            Assignee: zhijiang
             Fix For: 1.9.0


The {{NetworkEnvironment}} would be refactored into {{NetworkShuffleService}} created by {{ShuffleManager}} future. So the {{NetworkEnvironment}} should only cover shuffle related components to make the preparation.

Currently {{KvStateRegistry}}, {{KvStateServer}}, {{KvStateClientProxy}} are not related to shuffle process and mainly used to be got in {{TaskExecutor}}. So it is reasonable to remove them from {{NetworkEnvironment}}.

And then we could introduce a new {{KvStateService}} for wrapping these three components and pass it into {{TaskManagerService}}. This new service can also be passed into {{TaskExecutor,}} {{Task}} for use and avoid spreading in messy.
