Review Comment:
   `create_routine_params` and `create_routine_options` are not required,
   refer to /hive/hplsql/src/main/antlr4/org/apache/hive/hplsql/Hplsql.g4,

   we keep the same grammar as hplsql, such as:
   `DROP PROCEDURE (IF EXISTS)? name=multipartIdentifier`
   or
   `DROP (PROCEDURE | PROC) (IF EXISTS)? name=multipartIdentifier`
