Description

Enhancement 为了方便调试和测试，增加改写开关和某个规则的开关。

可以使用配置项或者会话变量的方式实现。 note: 现在会话变量不支持查看，也没有global session的区别。参考 #235

前置依赖任务 #344

Contributor guide

Research direction
Understand the existing rewriting rules implementation and how configuration or session variables are handled. Check referenced issues #235 and #344 for context. Then add a mechanism to enable/disable rewriting globally and per rule.
