Add dedicated property classes for the Chat and the Embedding models and use a common connection properties for both:
- OpenAiConnectionProperties (baseUrl, apiKey) with prefix spring.ai.openai.*.
- OpenAiChatProperties (model, temperature) with prefix spring.ai.openai.chat.
- OpenAiEmbeddingProperties (model) with prefix spring.ai.openai.embedding.*
Additionally the OpenAiChatProperties and OpenAiEmbeddingProperties can optionally override the OpenAiConnectionProperties
so that we can use the Chat model from one Provider and the Embedding model from another.
