### What problem does this PR solve?
Add GPUStack as a new model provider.
[GPUStack](https://github.com/gpustack/gpustack) is an open-source GPU
cluster manager for running LLMs. Currently, locally deployed models in
GPUStack cannot integrate well with RAGFlow. GPUStack provides both
OpenAI compatible APIs (Models / Chat Completions / Embeddings /
Speech2Text / TTS) and other APIs like Rerank. We would like to use
GPUStack as a model provider in ragflow.

Related issue: https://github.com/infiniflow/ragflow/issues/4064.

Remove Redundant None Check for vector_similarity_weight (#4037)
### What problem does this PR solve?
The removed if statement is unnecessary and adds cognitive load for
readers.
The original code:
```
vector_similarity_weight = req.get("vector_similarity_weight", 0.3)
if vector_similarity_weight is None:
vector_similarity_weight = 0.3
```
has been simplified to:
```
vector_similarity_weight = req.get("vector_similarity_weight", 0.3)
```
