Spring-ai Refactor and centralize Retry logic

• Establish a new "spring-ai-retry" project, implementing a default HTTP error handler, RetryTemplate, and handling both Transient and Non-Transient Exceptions.
• Streamline existing clients (e.g., OpenAI and MistralAI) to utilize "spring-ai-retry."
• Integrate retry auto-configuration with customizable properties, extending it to OpenAI and MistralAI Auto-Configs.
• Allow configuration of RetryTemplate and ResponseErrorHandler for various clients, including OpenAIChatClient, OpenAiEmbeddingClient, OpenAiAudioTranscriptionCline, OpenAiImageClient, MistralAiChatClient, and MistralAiEmbeddingClient.
• Add tests for default RestTemplate and ResponseErrorHandler configurations in OpenAI and MistralAI.
• Introduce new retry auto-config properties: "noRetryOnHttpClientErrors" and "noRetryOnHttpCodes."
• Implement tests for retry auto-config properties.
• Generate missing license headers.
