需求来源：

mysql 8.19客户端会发送，{SELECT COUNT() FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'xxx' UNION SELECT COUNT() FROM information_schema.COLUMNS WHERE TABLE_SCHEMA = 'xxx' UNION SELECT COUNT(*) FROM information_schema.ROUTINES WHERE ROUTINE_SCHEMA = 'xxx' }语句，mycat报找不到表错误

方案

完善路由代码，增加对 information_schema.TABLES union all语句的支持
