             Summary: Add SQL thread pools metrics
                 Key: IGNITE-25638
                 URL: https://issues.apache.org/jira/browse/IGNITE-25638
             Project: Ignite
          Issue Type: Improvement
            Reporter: Vyacheslav Koptilin
            Assignee: Vyacheslav Koptilin


Need to consider adding appropriate metrics for SQL thread pools, like we have 
in Apache Ignite 2 
[https://ignite.apache.org/docs/latest/monitoring-metrics/new-metrics#thread-pools]

The following thread pools should be added to monitoring:
 * sql-planning-pool - this thread pool is used to plan SQL queries
 * sql-execution-pool - this thread pool is used to execute SQL fragments of 
complex queries

Note that SQL execution always starts in a caller thread and might be switched 
to another one under some circumstances, like there is no plan in the SQL cache.
