beliefer 2d3692ed45 [SPARK-31406][SQL][TEST] ThriftServerQueryTestSuite: Sharing test data and test tables among multiple test cases 
### What changes were proposed in this pull request?
This PR is related to https://github.com/apache/spark/pull/28060.
`ThriftServerQueryTestSuite` spend 17 minutes time to test.
I checked the code and found `ThriftServerQueryTestSuite` load test data repeatedly.
I've listed all the test cases order by time with desc in the `hive-thriftserver` module below.

Class | Spend time  ↑ | Failure | Skip | Pass | Total test case
-- | -- | -- | -- | -- | --
ThriftServerQueryTestSuite | 17 minutes | 0 | 15 | 140 | 155
CliSuite | 8 minutes 24 seconds | 0 | 0 | 24 | 24
SparkThriftServerProtocolVersionsSuite | 59 seconds | 0 | 0 | 210 | 210
HiveThriftBinaryServerSuite | 36 seconds | 0 | 1 | 21 | 22
SparkMetadataOperationSuite | 19 seconds | 0 | 0 | 7 | 7
HiveCliSessionStateSuite | 16 seconds | 0 | 0 | 2 | 2

UISeleniumSuite | -1 millseconds | 0 | 1 | 0 | 1

I checked the code of `ThriftServerQueryTestSuite` and found `ThriftServerQueryTestSuite` load test data repeatedly.
This PR will improve the performance of `ThriftServerQueryTestSuite`.
Because https://github.com/apache/spark/pull/28060 provides `createTestTables`(e42a3945ac/sql/core/src/test/scala/org/apache/spark/sql/SQLQueryTestSuite.scala (L574)) and `removeTestTables`(e42a3945ac/sql/core/src/test/scala/org/apache/spark/sql/SQLQueryTestSuite.scala (L666)), this PR will still uses them.
The total time run `ThriftServerQueryTestSuite` before and after this PR show below.
Before
No | Time
-- | --
1 | 18 minutes, 8 seconds
2 | 22 minutes, 44 seconds
3 | 17 minutes, 48 seconds
4 | 18 minutes, 30 seconds

After
No | Time
-- | --
1 | 16 minutes, 11 seconds
2 | 17 minutes, 19 seconds
3 | 18 minutes, 15 seconds
4 | 17 minutes, 27 seconds

### Why are the changes needed?
Improve the performance of `ThriftServerQueryTestSuite`.

### Does this PR introduce any user-facing change?
'No'.

### How was this patch tested?
Jenkins test

Closes #28180 from beliefer/avoid-load-thrift-test-data-repeatedly.

Spark SQL

This module provides support for executing relational queries expressed in either SQL or the DataFrame/Dataset API.

Spark SQL is broken up into four subprojects:

  • Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
  • Execution (sql/core) - A query planner / execution engine for translating Catalyst's logical query plans into Spark RDDs. This component also includes a new public interface, SQLContext, that allows users to execute SQL or LINQ statements against existing RDDs and Parquet files.
  • Hive Support (sql/hive) - Includes extensions that allow users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allow users to run queries that include Hive UDFs, UDAFs, and UDTFs.
  • HiveServer and CLI support (sql/hive-thriftserver) - Includes support for the SQL CLI (bin/spark-sql) and a HiveServer2 (for JDBC/ODBC) compatible server.

Running ./sql/create-docs.sh generates SQL documentation for built-in functions under sql/site, and SQL configuration documentation that gets included as part of configuration.md in the main docs directory.
