## What changes were proposed in this pull request?
Currently SQL tab in the WEBUI doesn't support pagination. Because of that following issues are happening.
1) For large number of executions, SQL page is throwing OOM exception (around 40,000)
2) For large number of executions, loading SQL page is taking time.
3) Difficult to analyse the execution table for large number of execution.
[Note: spark.sql.ui.retainedExecutions = 50000]
All the tabs, Jobs, Stages etc. supports pagination. So, to make it consistent with other tabs
SQL tab also should support pagination.
I have followed the similar flow of the pagination code in the Jobs and Stages page for SQL page.
Also, this patch doesn't make any behavior change for the SQL tab except the pagination support.
## How was this patch tested?
bin/spark-shell --conf spark.sql.ui.retainedExecutions=50000
Run 50,000 sql queries.
