Kent Yao abc8ccc37b [SPARK-31926][SQL][TESTS][FOLLOWUP][TEST-HIVE1.2][TEST-MAVEN] Fix concurrency issue for ThriftCLIService to getPortNumber ... ### What changes were proposed in this pull request? This PR brings https://github.com/apache/spark/pull/28751 back - It once reverted by 4a25200 because of inevitable maven test failure - See related updates in this followup a0187cd6b5 - And reverted again because of the flakiness of the added unit tests - In this PR, The flakiness reason found is caused by the hive metastore connection that the SparkSQLCLIService trying to create which turns out is unnecessary at all. This metastore client points to a dummy metastore server only. - Also, add some cleanups for SharedThriftServer trait in before and after to prevent its configurations being polluted or polluting others ### Why are the changes needed? fix flaky test ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? passing sbt and maven tests Closes #28835 from yaooqinn/SPARK-31926-F.
