URL: https://github.com/apache/flink/pull/18296
## What is the purpose of the change
*When the config
high-availability.zookeeper.client.tolerate-suspended-connections is default

old appMaster will clean up all the HA data and the new appMaster will not
recover from the latest checkpoint. We will fix it.*
## Brief change log
- *When cluster is shutting down with ApplicationStatus.UNKNOWN,
cleanupHaData will be set false to retain HA data.*
