After this PR, the service named service discovery will be a child service of frontend service and it's optional.
A servalable will contain a backend and a list of frontends, the former one stay AS-IS and the latter is changed from single to multiple, which means a serverable can have multiple interfaces to interact with its different clients

### 1. Description
EngineRef use exists znode to determine whether engine started successfully or not(use the last znode), there are inconsistencies in this. So, take an idea to improve the detection mechanism by adding the started sessionid to the znone. `EngineRef` will check the sessionid in a loop after a engine started.
### 2. Here are two options
**Option I, add sesssionid to the data of znode**
**Option II, add sessionid to the path of znode**
### 3. Solution
In order to be consistent with the design of server znode, prefer to choose _Option II_ .
**Demo**

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.
