---------------------------------

             Summary: The execution.attached=true parameter does not take effect in application mode
                 Key: FLINK-38118
                 URL: https://issues.apache.org/jira/browse/FLINK-38118
             Project: Flink
          Issue Type: Bug
          Components: Client / Job Submission
    Affects Versions: 1.20.2, 2.0.0
            Reporter: shilei-ly


In FLINK-35625, flink merged the per-job mode and application mode. Currently, flink1.20 and flink2.x only support application mode, but in application mode, the *execution.attached=true* and *execution.shutdown-on-attached-exit=true* parameter has no effect. I think application mode should support these parameters, because attach mode is very useful in some scenarios, such as using attach mode in dolphinscheduler scheduler to monitor flink cluster status.

The functions of these parameters are as follows:
1. After submitting the task through {*}flink run -Dexecution.attached=true xxx.jar{*}, the flink client process keeps running until the application cluster stops.
2. After submitting the task through {*}flink run -Dexecution.attached=true -Dexecution.shutdown-on-attached-exit=true xxx.jar{*}, the flink client can control the life cycle of the application cluster. When ctrl + c stops the flink client process, the application cluster should stop all jobs and stop the cluster.

I think we can do this through flink client heartbeat. [~xtsong]  [~fcsaky]  [~gaborgsomogyi]   Can you give me some suggestions? I want to submit a PR to fix this bug.
