Description

During Spark 3.3, we added code-gen for FULL OUTER shuffled hash join, FULL OUTER sort merge join, and Existence sort merge join. Given the join test coverage is not high, and we would love to avoid any upcoming release regression due to it. So here we introduce three internal configs to allow users and developers to disable code-gen in case we found any bug after release.
