* 添加LLM模型切换功能，需要在server_config中设置可切换的模型 * add tests for api.py/llm_model/* * - 支持模型切换 - 支持智普AI线上模型 - startup.py增加参数`--api-worker`，自动运行所有的线上API模型。使用`-a (--all-webui), --all-api`时默认开启该选项 * 修复被fastchat覆盖的标准输出 * 对fastchat日志进行更细致的控制，startup.py中增加-q(--quiet)开关，可以减少无用的fastchat日志输出 * 修正chatglm api的对话模板 Co-authored-by: liunux4odoo <liunu@qq.com>
