Gengliang Wang 8e11f5f007 [SPARK-35576][SQL] Redact the sensitive info in the result of Set command 
### What changes were proposed in this pull request?

Currently, the results of following SQL queries are not redacted:
```
SET [KEY];
SET;
```
For example:

```
scala> spark.sql("set javax.jdo.option.ConnectionPassword=123456").show()
+--------------------+------+
|                 key| value|
+--------------------+------+
|javax.jdo.option....|123456|
+--------------------+------+

scala> spark.sql("set javax.jdo.option.ConnectionPassword").show()
+--------------------+------+
|                 key| value|
+--------------------+------+
|javax.jdo.option....|123456|
+--------------------+------+

scala> spark.sql("set").show()
+--------------------+--------------------+
|                 key|               value|
+--------------------+--------------------+
|javax.jdo.option....|              123456|

```

We should hide the sensitive information and redact the query output.

### Why are the changes needed?

Security.

### Does this PR introduce _any_ user-facing change?

Yes, the sensitive information in the output of Set commands are redacted

### How was this patch tested?

Unit test

Closes #32712 from gengliangwang/redactSet.

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.
