For instance, 1. If you add a feature, you can talk about the use case of it. 2. If you fix a bug, you can clarify why it is a bug. --> 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. ### _How was this patch tested?_ - [x] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [ ] Add screenshots for manual tests if appropriate - [x] [Run test](https://kyuubi.readthedocs.io/en/latest/tools/testing.html#running-tests) locally before make a pull request Closes #627 from yaooqinn/multipleengines.
