Before this PR, Subquery reuse does not work. Below are three issues: - Subquery reuse does not work. - It is sharing the same `SQLConf` (`spark.sql.exchange.reuse`) with the one for Exchange Reuse. - No test case covers the rule Subquery reuse. This PR is to fix the above three issues. - Ignored the physical operator `SubqueryExec` when comparing two plans. - Added a dedicated conf `spark.sql.subqueries.reuse` for controlling Subquery Reuse - Added a test case for verifying the behavior N/A Author: Xiao Li <gatorsmile@gmail.com> Closes #18169 from gatorsmile/subqueryReuse. (cherry picked from commit f7cf2096fdecb8edab61c8973c07c6fc877ee32d) Signed-off-by: Xiao Li <gatorsmile@gmail.com>
