[Feature]: Add volcengine/deepseek-r1

[issac2e]

The Feature

Adding Deepseek-R1 deployed on volcengine, volcengine has supported the r1 model, but there is no reasoning_content in the r1 response parameters, can you add it?

Motivation, pitch

I am trying to access the Deepseek-R1 model through volcengine, and I can get the response result, but I found that "reasoning_content" parameters are missing in the response result, and I hope to adapt it

Inference content for the expected response body:
{
"choices": [
{
"finish_reason": "stop",
"index": 0,
"logprobs": null,
"message": {
"content": ".....",
"reasoning_content": ".....",
"role": "assistant"
}
}
],
