[PATCH proxmox 2/4] s3-client: add 429 HTTP status code as retryable

[Christian Ebner <c.ebner@proxmox.com>]

When enforcing request rate limits, providers might return HTTP
status code 429 signaling too may requests. Since on retry there
will be a backoff time and the request rate limiter will be checked
again, retry requests which returned this status codes as well.
