   The pod executing the task is not deleted, it is visible in kubernetes but with a different name.
   
   Pod creation happens in the scheduler, `kubernetes_executor.run_pod_async`. Here the real name is generated that is sent to kubernetes.
   
   However, if i understand the flow correctly, the RenderedTaskInstanceFields is later created inside the pod itself, via the local executor when it calls `taskinstance._execute_task_with_callbacks`
   
                   rtif = RenderedTaskInstanceFields(ti=self, render_templates=False)
                   RenderedTaskInstanceFields.write(rtif)
                   RenderedTaskInstanceFields.delete_old_records(self.task_id, self.dag_id)
   
   RenderedTaskInstanceFields calls ti.render_k8s_pod_yaml() which calls `construct_pod`, where the pod name is regenerated using `make_unique_pod_id`, which as the name suggests is random and a new unique value :)
