Review Comment:
this should be an internal flag -we can remove it anytime
I think the issue could also be addressed by YARN-10333 (correct me if I'm
wrong), so the docs might be
"When `${ENGINE_FLINK_DOAS_ENABLED.key}=true` and neither FLINK-35525 (Flink
1.20.0) nor YARN-10333 (Hadoop 3.4.0) is available, enable this configuration
to generate a temporary HADOOP_TOKEN_FILE that will be picked up by the Flink
engine bootstrap process."
