[GitHub] [flink] XComp opened a new pull request, #19353: [FLINK-27050][runtime] Removes default RpcSystem instance

XComp opened a new pull request, #19353:
URL: https://github.com/apache/flink/pull/19353

   
   
   ## What is the purpose of the change
   
   Having a default RpcSystem in TestingDispatcher.Builder
   caused threads being spawned without cleanup. Instead, we
   should rely on the RpcSystem instance provided by the test.
   
   ## Brief change log
   
   * Removed the default instance from TestingDispatcher.Builder and made it a required parameter through the `build` method
   
   ## Verifying this change
   
   * Running a test manually in a loop and checking that there are no threads left hanging, e.g. in `DispatcherCleanupResourcesTest`:
   ```
       @Test
       public void foo() throws Exception {
           for (int i = 0; i < 100; i++) {
               setup();
               testDuplicateJobSubmissionDoesNotDeleteJobMetaData();
               teardown();
           }
   
           System.out.println("Stop the debugger here");
       }
   ```

   I'm investigating the OOM in the integration tests of the `flink-tests` module ([ci run](https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=34234&view=logs&j=a57e0635-3fad-5b08-57c7-a4142d7d6fa9&t=2ef0effc-1da1-50e5-c2bd-aab434b1c5b7)). In the mean time, I'm gonna start another ci run
