Extend Dev Proxy with LLM

[waldekmastykarz]

• extend Dev Proxy config with new properties
  • llmUrl (optional, default null)
  • model (optional, default to phi3)
• extend ProxyContext with an LLM class responsible for communicating with an LLM, as specified in the config. The class exposes the GenerateCompletion method which calls to LLM to get a completion for the specified prompt. If calling an LLM failed, it returns null.
• extend the OpenApiSpecGeneratorPlugin to use LLM for:
  • generating operationId from the operation path and method
  • generating operation description from the operation path and method
  • generating API description from the list of operations and methods
• publish docs to explain how to use an LLM with Dev Proxy
