   @yangzhg @morningman Hi, The sql_parser.cup file seems has conflict issue  frequently. could we put a readme file or some useful link under `fe/fe-core/src/main/cup/` directory? which is friendly for new contributor.

   It is difficult to describe clearly how to write a cup file with simple sentences, but we can attach a link to the cup syntax

   If we resolve the reduce conflict, I suggest to modify the `expectedConflicts` in `fe/fe-core/pom.xml` too.
