CliSuite has been flaky for a while, this PR tries to improve this situation by fixing a race condition in CliSuite. The captureOutput function is used to capture both stdout and stderr output of the forked external process in two background threads and search for expected strings, but wasn't been properly synchronized before.

[SPARK-3971][SQL] Backport apache#2843 to branch-1.1
64945f8 
This PR backports apache#2843 to branch-1.1. The key difference is that this one doesn't support Hive 0.13.1 and thus always returns `0.12.0` when `spark.sql.hive.version` is queried.

6 other commits on which apache#2843 depends were also backported, they are:

- apache#2887 for `SessionState` lifecycle control
- apache#2675, apache#2823 & apache#3060 for major test suite refactoring and bug fixes
- apache#2164, for Parquet test suites updates
- apache#2493, for reading `spark.sql.*` configurations
