[Proposal] Enhanced Config with more customisation flexibility

[chao-peng]

Describe the feature you want to propose

Currently, models and providers are bounded. I am thinking to support the following configuration format:

trae-agent:
    max_steps: 20
    enable_lakeview: true
    model: model_1
another-feature-agent:
    max_steps: 20
    enable_lakeview: true
    model: model_1
model_providers:
    openai:
        api_key: your_openai_api_key
        base_url: base_url
    anthropic:
        api_key: your_anthropic_api_key
        base_url: base_url
models:
    model_1:
        model_name: gpt-4o
        provider: openai
        max_tokens: 128000

The benefit is that we can also configure agents, with flexible model selections.

What problem does this feature solve or what benefit does it bring?

Flexible agent and model configuration

Will raise a PR for us to try this format, while maintaining the current configuration for backward compatibility.
