Description
Currently, we do not allow select query with a lock to be executed on mysql outside of a transaction. In MySQL, this is a lock no-op.
Therefore this change is to no handle this case and treat it like a select query and allow it to be executed outside of transaction. For Vitess also it will be a lock no-op.
