Probably if we implement just retry strategy - needRetry could be an external logic instead of hardcoded one.
So we'll be able to check anything inside response to decide if retry needed.

Implemented a retry interceptor to handle retry logic for failed network requests with status codes 500-599, up to three retries with exponential backoff.
