### Description of PR
Refer to HDFS-17504.
BPServiceActor is a very important thread. In a non-HA cluster, the exit of
the BPServiceActor thread will cause the DN process to exit. However, in a HA
cluster, this is not the case.
I found HDFS-15651 causes BPServiceActor thread to exit and sets the
"runningState" from "RunningState.FAILED" to "RunningState.EXITED", it can be
confusing during troubleshooting.
I believe that the DN process should exit when the flag of the
BPServiceActor is set to RunningState.FAILED because at this point, the DN is
unable to recover and establish a heartbeat connection with the ANN on its own.
