### 1. Describe the feature
Kyuubi use `TestingServer` as the EmbeddedZookeeper service in codebase, and require many args to init the service. These `electionPort`, `quorumPort`, `serverId` parameters only work in cluster mode, these ports are not bound to the host.
From hadoop and bookkeeper project, they use `ZooKeeperServer` as a built-in zk service, especially the bookeeper project.

- https://github.com/apache/bookkeeper/blob/master/bookkeeper-server/src/main/java/org/apache/bookkeeper/shims/zk/ZooKeeperServerShimImpl.java
### 2. Describe the solution
Improve
- Remove `electionPort`, `quorumPort`, `serverId` which are nerver be used, hadoop and bookkeer do the same
- Replace `TestingServer` with `ZooKeeperServer`
- Remove `curator-test` dependency
### 3. `deleteDataDirectoryOnClose`
The name style for `deleteDataDirectoryOnClose` option, refer to hadoop `core-default.xml`
https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/core-default.xml
```
hadoop.security.dns.log-slow-lookups.enabled
hadoop.security.dns.log-slow-lookups.threshold.ms
