[SPARK-32003][CORE] Unregister outputs for executor on fetch failure …
…after executor is lost If an executor is lost, the `DAGScheduler` handles the executor loss by removing the executor but does not unregister its outputs if the external shuffle service is used. However, if the node on which the executor runs is lost, the shuffle service may not be able to serve the shuffle files. In such a case, when fetches from the executor's outputs fail in the same stage, the `DAGScheduler` again removes the executor and by right, should unregister its outputs. It doesn't because the epoch used to track the executor failure has not increased. We track the epoch for failed executors that result in lost file output separately, so we can unregister the outputs in this scenario.
