feat: add back-off request

[muhfaris]

add module to support back-off request

1. Initial Retry: When a request fails, the client initiates a retry immediately or after a short delay.

2. Exponential Increase: If the retry fails again, the client increases the waiting time before the next retry exponentially. For example, the client might wait 1 second after the first failure, then 2 seconds after the second failure, 4 seconds after the third failure, and so on.

3. Maximum Backoff Time: There is usually a maximum limit to the backoff time. After reaching this limit, subsequent retries may use the maximum backoff time.

4. Jitter: Some implementations also include jitter to add a random factor to the waiting time, which helps avoid synchronization effects when multiple clients are retrying simultaneously.
