1. refine the zk lock to lock only during engine bootstrapping, not wrap the part that only gets the address of engines. This can significantly reduce overhead.
2. add tests for the locking proccess.
### _How was this patch tested?_

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.

TL;DR The UnboundID LDAP SDK for Java has much friendly API and zero dependencies.
https://ldap.com/unboundid-ldap-sdk-for-java/
Apache Directory Service vs UnboundID LDAP SDK
1. Apache Directory Service is quite heavy stuff compare to our requirement, we just need a embedded LDAP server for UT.
2. The API of Apache Directory Service and Java Naming are not straightforward, because it's not specifically designed for LDAP.
3. Apache Directory Service provided a single fat-jar contains dependencies which aren't relocated.

In connection level, we will release engine if the session connection is closed but we don't clean up the discovery service (i.e. the namespace in zookeeper). That may cause the disk stress after running a long time.
