Add support for VolcEngine - the current version supports SDK2 (#885)
- The main idea is to assemble **ak**, **sk**, and **ep_id** into a
dictionary and store it in the database **api_key** field
- I don’t know much about the front-end, so I learned from Ollama, which
may be redundant.
### Configuration method
- model name
- Format requirements: {"VolcEngine model name":"endpoint_id"}
- For example: {"Skylark-pro-32K":"ep-xxxxxxxxx"}
- Volcano ACCESS_KEY
- Format requirements: VOLC_ACCESSKEY of the volcano engine
corresponding to the model
- Volcano SECRET_KEY
- Format requirements: VOLC_SECRETKEY of the volcano engine
corresponding to the model
