Implement retry for LLMClient

[danielchalef]

This pull request implements retry functionality for the LLMClient class in the client.py file. The _generate_response_with_retry method has been added, which retries the generation of a response in case of a server error. The tenacity library is used for the retry logic. This enhancement improves the reliability of the client by handling temporary server errors gracefully.

  The _is_server_error method should be used to check an instance of an exception, not the exception class itself. Pass the exception instance to _is_server_error.

  Consider expanding the retry logic to handle other transient errors, such as network issues, not just server errors. This can improve the robustness of the retry mechanism.

  The retry logic is implemented using the tenacity library, which is a good choice for handling retries. However, the retry logic is only applied to server errors (HTTP 5xx). The code should also handle other types of transient errors, such as network issues, which are not currently covered by the is_server_error function.

• Draft comment:
  Consider adding comments to explain the retry logic in _generate_response_with_retry for better clarity.
• Reason this comment was not posted:
  Confidence changes required: 50%
  The code is mostly well-structured, but there are a few areas that could be improved for clarity and maintainability.
