### Description of PR
HDFS-17575
This is a continue work on #6933.
Currently, a SaslDataTransferClient may send a message without using its
SaslParticipant as below.
```java
sendSaslMessage(out, new byte[0]);
```
Instead, it should use its SaslParticipant to create the response.
```java
byte[] localResponse =
sasl.evaluateChallengeOrResponse(remoteResponse);
sendSaslMessage(out, localResponse);
```
