### _Why are the changes needed?_ When communicating with NameNode HA, private tokens are created from original token:  In above image, "ha-hdfs:mycluster" is the original token. "ha-hdfs://192.168.56.101:8020" and "ha-hdfs://192.168.56.102:8020" are private tokens. `KyuubiHadoopUtils.getCredentialsInternal` was supposed to extract these private tokens at Kyuubi server side and send them to SQL engine. But in fact, SQL engine side private tokens are automatically created when adding original token, inside `org.apache.hadoop.security.Credentials#addToken`. ### _How was this patch tested?_ - [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [x] Add screenshots for manual tests if appropriate SequenceNumber of private tokens always equal to original token:   - [x] [Run test](https://kyuubi.readthedocs.io/en/latest/develop_tools/testing.html#running-tests) locally before make a pull request -- This is an automated message from the Apache Git Service.
