iRakson fbb3144a9c [SPARK-31642] Add Pagination Support for Structured Streaming Page 
### What changes were proposed in this pull request?
Add Pagination Support for structured streaming page. Now both tables `Active Queries` and `Completed Queries` will have pagination.
To implement pagination, pagination framework from #7399  is used.
* Also tables will only be shown if there is at least one entry in the table.

### Why are the changes needed?
* This will help users in analysing their structured streaming queries in much better way.
* Other Web UI pages support pagination in their table. So this will make web UI more consistent across pages.
* This can prevent potential OOM errors.

### Does this PR introduce _any_ user-facing change?
Yes. Both tables will support pagination.

### How was this patch tested?
Manually. I will add snapshots soon.

Closes #28485 from iRakson/SPARK-31642.

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.
