HTTPRetry

Wraps the HTTP operations (GET, POST, PUT, DELETE, multipart SEND) with retry on network errors.

Used through the shared httpr instance by all CAWS services.

Key points:

• Retries only on SocketException or TimeoutException; HTTP error responses are returned as-is.
• Makes up to 15 attempts with exponential backoff (from the retry package), each delay capped at 30 seconds.
• Each attempt times out after 20 seconds (15 for DELETE, 5 for SEND).
