Feature Proposal: Allow customization of initial system prompt

like #175

AutoDev is currently unable to work with LM Studio:

It only seems to affect the "test llm connection"

I post the successful experience of LM Studio here for others to reuse. Note: Since AutoDev currently only obtains content from the first message returned, SSE mode is not supported and "stream" in the body parameter should be set to false.

llm server: Custom
server: http://localhost:1234/v1/chat/completions
response(json path): $.choices[0].message.content
request body(json): {"customHeaders":{"Content-Type":"application/json"},"customFields":{"model":"lmstudio-community/Meta-Llama-3-8B-Instruct-GGUF","temperature":0.7,"max_tokens":-1,"stream":false}}
