[KYUUBI #1629] Flink backend implementation
### _Why are the changes needed?_ This PR covers #1619. Overall, this PR contains the following changs, 1. change `build/dist` script to support flink sql engine 2. enhance `externals/flink-sql-engine/pom.xml` to support create a shaded jar 3. simplify `externals/kyuubi-flink-sql-engine/bin/flink-sql-engine.sh` 4. introduce `FlinkSQLEngine`(flink sql engine entrypoint) and `FlinkProcessBuilder`(kyuubi server launcher) 5. add ut in kyuubi server side After this PR, we can run the basic query e.g. `select now()` from beeline and get result, and Kyuubi Server can auto launch flink engine if there is no proper one. The Flink engine also supports other engine share levels defined in Kyuubi. The implementation based on Flink 1.14 codebase. ### _How was this patch tested?_ - [ ] 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/develop_tools/testing.html#running-tests) locally before make a pull request Closes #1629 from pan3793/flink-backend.
