Add a new logical plan optimization: When there is a Project (KEEP/DROP/RENAME/renaming EVALs) in a LOOKUP JOIN's left child (the "main" side), perform the Project after the LOOKUP JOIN. This prevents premature field extractions when the lookup join happens on data nodes. (cherry picked from commit 809dab1) # Conflicts: # x-pack/plugin/esql/src/test/java/org/elasticsearch/xpack/esql/optimizer/LogicalPlanOptimizerTests.java # x-pack/plugin/esql/src/test/java/org/elasticsearch/xpack/esql/plan/logical/CommandLicenseTests.java
