Peter Toth 9e12c94c15 [SPARK-29359][SQL][TESTS] Better exception handling in (SQL|ThriftServer)QueryTestSuite
### What changes were proposed in this pull request?
This PR adds 2 changes regarding exception handling in `SQLQueryTestSuite` and `ThriftServerQueryTestSuite`
- fixes an expected output sorting issue in `ThriftServerQueryTestSuite` as if there is an exception then there is no need for sort
- introduces common exception handling in those 2 suites with a new `handleExceptions` method

### Why are the changes needed?

Currently `ThriftServerQueryTestSuite` passes on master, but it fails on one of my PRs (https://github.com/apache/spark/pull/23531) with this error  (https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/111651/testReport/org.apache.spark.sql.hive.thriftserver/ThriftServerQueryTestSuite/sql_3/):
```
org.scalatest.exceptions.TestFailedException: Expected "
[Recursion level limit 100 reached but query has not exhausted, try increasing spark.sql.cte.recursion.level.limit
org.apache.spark.SparkException]
", but got "
[org.apache.spark.SparkException
Recursion level limit 100 reached but query has not exhausted, try increasing spark.sql.cte.recursion.level.limit]
" Result did not match for query #4 WITH RECURSIVE r(level) AS (   VALUES (0)   UNION ALL   SELECT level + 1 FROM r ) SELECT * FROM r
```
The unexpected reversed order of expected output (error message comes first, then the exception class) is due to this line: https://github.com/apache/spark/pull/26028/files#diff-b3ea3021602a88056e52bf83d8782de8L146. It should not sort the expected output if there was an error during execution.

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

### How was this patch tested?
Existing UTs.

Closes #26028 from peter-toth/SPARK-29359-better-exception-handling.

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.
