feat: enhance request handling with improved retry logic and logging

[magic3007]

• Added logging for retryable errors and retry attempts in the request module.
• Increased the maximum number of retry attempts from 3 to 5.
• Updated the exponential backoff strategy for retries, with a multiplier of 2 and adjusted min/max wait times.
• Increased the default timeout for requests from 10 to 30 seconds.
• Improved error handling to log connection and timeout errors.

These changes aim to provide better visibility into request failures and enhance the robustness of the request handling process.

Thanks for sending the PR!

We had some relevant discussion in this thread: adding these retry in the send_request function is going to cause issue somewhere 😓
#6175 (comment)

Maybe it is better to handle retry here:
