minor changes, cppgen was removed from cypher, query_engine should for now contain that kind of logic

DISTINCT is now inside AST; tradeoff: [Return object with return list and distinct pointers -> query executor is going to be more complex] OR [ReturnList object and ReturnDistinct object -> lemon / LARL(1) syntax will be much more complex]

implemented a lockfree list

Summary: It's not the fastest for all operations but it's efficient on inserts to front and list traversals. removes are quite slow but it's not important because remove is only used by the garbage collector.
Test Plan: Reason wisely
