### _Why are the changes needed?_
Introduce a brand new CHAT engine, it's supposed to support different backends, e.g. ChatGPT, 文心一言, etc.
This PR implements the following providers:
- ECHO, simply replies a welcome message.
- GPT: a.k.a ChatGPT, powered by OpenAI, which requires a API key for authentication. https://platform.openai.com/account/api-keys
Add the following configurations in `kyuubi-defaults.conf`
```
kyuubi.engine.chat.provider=[ECHO|GPT]
kyuubi.engine.chat.gpt.apiKey=<chat-gpt-api-key>
```
Open an ECHO beeline chat engine.
```
beeline -u 'jdbc:hive2://localhost:10009/?kyuubi.engine.type=CHAT;kyuubi.engine.chat.provider=ECHO'
```
```
Connecting to jdbc:hive2://localhost:10009/
