[PR] [FLINK-37822][tests] Fix flaky test: OpenTelemetryMetricReporterITCase.testReport [flink]

Izeren opened a new pull request, #26650:
URL: https://github.com/apache/flink/pull/26650

   ## What is the purpose of the change
   Address flakiness of the test: `OpenTelemetryMetricReporterITCase.testReport`
   
   ## Brief change log
   Adding `@VisibleForTesting OpenTelemetryMetricReporter#waitForLastReportToComplete` method to allow synchronous use of `OpenTelemetryMetricReporter#report` in tests.
   
   ## Verifying this change
   
   This change is already covered by existing tests, such as `OpenTelemetryMetricReporterITCase`. 
   To ensure it is not flaky, I have run it locally as `@RepeatedTest(100)` with no issues (previously, fail rate was around 30%).
   
   ## Does this pull request potentially affect one of the following parts:
   
     - Dependencies (does it add or upgrade a dependency): no
     - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no
     - The serializers: no
     - The runtime per-record code paths (performance sensitive): no
     - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no
     - The S3 file system connector: no

     - Does this pull request introduce a new feature? no
     - If yes, how is the feature documented? not applicable
