This pull request implements #6052

Describe Your Solution 🔧

This PR introduced a new config kyuubi.ha.engine.cleanup.enabled.

If kyuubi.ha.engine.cleanup.enabled is set to true, Engine will delete namespace node and lock node on ZooKeeper when stops.
This feature can be used to cleanup ZooKeeper nodes created by Engine with random subdomains.

Note: User should guarantee Engine with same namespace won't be launched before old Engine stops. Otherwise, errors may happen when launching new Engine.

Looks a little bit dangerous, WDYT @yaooqinn?

Forward ideas from offline discussion, an alternative approach is providing CLI tool to allow administrators to manually clean the subdomain nodes
