### 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

This PR adds multiple engine support for non-connection share levels. A new configuration called `kyuubi.engine.share.level.sub.domain` is added for this functionality. For simplification, the configuration only accepts [1, 10]-length case insensitive string, only '_' and alphabets are valid.
Unlike connection mode, user mode supports the "long-running" feature across different JDBC connections. But the current implementation only is able to create one engine for a user. End-users don't want to put all eggs into one basket. It's not only less robust and flexible for a static engine to handle different workloads, and also hard to leverage failover when there is a zombied engine being cached.
With multiple engines support, end-users are able to
1. create as many engines as they want to meet the concurrency.
2. leverage different queue/namespace resource with long-running mode
3. can give different resources or priorities to their own engines for different workloads
4. can perform fast failover by creating a new sub domain
5. etc.

Manual cherry-pick some Spark patch into Kyuubi.
1. [Support query auto timeout cancel on thriftserver](https://github.com/apache/spark/pull/29933)
2. [Add config to control if cancel invoke interrupt task on thriftserver](https://github.com/apache/spark/pull/30481)
In order to keep backward with early Spark version, we hard code the config key instead of refer to Spark SQLConf.
Note that, the exists timeout of operator (`kyuubi.operation.idle.timeout`) is to cancel that client has no access with engine. That said if a query run a long time and the client is alive, the query would not be cancelled. Then the new added config `spark.sql.thriftServer.queryTimeout` can handle this case.
### _How was this patch tested?_
Add new test.

Currently, the engine starts to check its lifecycle during the session manager's startup without any initial delay. Before the engine gets ready finally, it might trigger self-terminating.
In this PR, we move the checker to the end where the engine is exposed to the servers.
Avoiding errors like:
