Docker容器内P4实例run_login()后password属性未更新致命令失败

在Docker容器内，对已连接的P4实例调用run_login()方法时，ticket文件能正常更新，但实例的password属性未同步更新，导致后续需要有效ticket的命令（如p4.run_fstat()）执行失败。容器外执行相同操作时，ticket文件更新的同时password属性会自动同步为ticket值。

容器内已正确配置以下P4环境变量：

• P4CONFIG
• P4TRUST
• P4TICKETS

手动将p4.password修改为ticket文件中的最新值后，p4.run_fstat()可正常运行。且容器内外的p4python与Python版本完全一致。
