Description

**描述你使用过程中遇到的问题: ** 客户端连接mycat后，执行: SET SESSION wait_timeout=1; show VARIABLES LIKE 'wait_timeout';

并得不到理想的值，这是因为什么机制呢，在官方文档中没有找到对应的说明。

Contributor guide

Research direction
Investigate how Mycat processes SET SESSION commands and how session variables are stored and retrieved. Trace the code path for SET SESSION wait timeout and SHOW VARIABLES to identify where the value is lost or not updated.
