feat(model): Support yi proxy LLM

[fangyinc]

Description

• Support yi proxy LLM

How Has This Been Tested?

1. Using yi proxyllm in DB-GPT webserver

# .env
LLM_MODEL=yi_proxyllm
YI_MODEL_VERSION=yi-34b-chat-0205
YI_API_BASE=https://api.lingyiwanwu.com/v1
YI_API_KEY={your-yi-api-key}

2. Using YiLLMClient
   Create python file test_yi_proxyllm.py

import asyncio

from dbgpt.core import ModelRequest
from dbgpt.model.proxy import YiLLMClient

client = YiLLMClient()
print(asyncio.run(client.generate(ModelRequest._build("yi-34b-chat-0205", "你是谁？"))))

Run test_yi_proxyllm.py

YI_API_KEY={your-yi-api-key} python test_yi_proxyllm.py

The output like this:

ModelOutput(text='我是一个人工智能助手，由零一万物公司开发。我是由工程师们编写代码，并通过算法提供各种信息和帮助的。我可以回答问题、编写文本以及提供各种帮助。我是通过学习大量的文本数据来sage={'completion_tokens': 60, 'prompt_tokens': 12, 'total_tokens': 72}, metrics=None)
