[Roadmap] Alibaba Cloud (Qwen) support

[KenMacD]

Why

Allow users to use Qwen models directly available through the Alibaba Cloud.

Description

Alibaba is the worlds third largest cloud. The AI models by the group are available at both an OpenAI-Compatible endpoint and their own SDK.

At the moment the https://dashscope-intl.aliyuncs.com/compatible-mode/v1/models lists follow, with the context and parameters being available in the docs.

{
  "object": "list",
  "data": [
    {
      "id": "qwen2-7b-instruct",
      "object": "model",
      "created": 1728632039,
      "owned_by": "system"
    },
    {
      "id": "qwen-max",
      "object": "model",
      "created": 1728632029,
      "owned_by": "system"
    },
    {
      "id": "qwen-plus",
      "object": "model",
      "created": 1728632023,
      "owned_by": "system"
    },
    {
      "id": "qwen-turbo",
      "object": "model",
      "created": 1728632018,
      "owned_by": "system"
    }
  ]
}

@KenMacD Alibaba Cloud Qwen models are fully supported. Enumeration is automatic, you only need to enter the API key - and optionally you can change the host. Uses the OpenAI compatibility service.

This includes cost computation, etc (note that I found out that there's caching behind the scenes but there's no discounted pricing for Caching for now).

Please give it a deep test and let me know if all is working to specifications.

Wow, that was quick. Thanks! Initial testing around prompts and files have all worked perfectly.
