[KYUUBI-SHADED #34] [KYUUBI-SHADED #33] Step 2/2: Port ZOOKEEPER-1718 to support JLine2 in ZK client 3.4

### _Why are the changes needed?_

This PR aims to port ZOOKEEPER-1718 to make the Zookeeper 3.4 to support JLine2.

To gain a clear change history, I propose to split the change into 2 PRs,

1. copy [org.apache.zookeeper.ZooKeeperMain](https://raw.githubusercontent.com/apache/zookeeper/release-3.4.14/zookeeper-server/src/main/java/org/apache/zookeeper/ZooKeeperMain.java) and [org.apache.zookeeper.JLineZNodeCompletor](https://raw.githubusercontent.com/apache/zookeeper/release-3.4.14/zookeeper-server/src/main/java/org/apache/zookeeper/JLineZNodeCompletor.java) from Apache Zookeeper v3.4.14 as-is
2. apply changes in ZOOKEEPER-1718

### _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

1. perform `build/mvn clean package` to generate `kyuubi-relocated-zookeeper-parent/kyuubi-relocated-zookeeper-34/target/kyuubi-relocated-zookeeper-34-0.3.0-SNAPSHOT.jar`
2. download and install [apache-kyuubi-1.8.0-bin.tgz](https://dlcdn.apache.org/kyuubi/kyuubi-1.8.0/apache-kyuubi-1.8.0-bin.tgz)
3. replace `KYUUBI_HOME/jars/kyuubi-shaded-zookeeper-34-0.1.0.jar` with `kyuubi-relocated-zookeeper-34-0.3.0-SNAPSHOT.jar`
4. replace `KYUUBI_HOME/jars/jline-0.9.94.jar` with `jline-2.14.6.jar`
5. perform `bin/kyuubi-zk-cli -server xxxxx:2181` to connect a Zookeeper cluster
6. check the logs to make sure JLine is enabled and run some command to check basic functionalities
```
