[pbs-devel] [PATCH proxmox 0/3] fix #6858: implement retry logic for transient API errors

[Christian Ebner]

These patches implement the best practice [0] on handling S3 API
response status codes 500 and 503 by retrying the requests after an
exponential backoff time.

The first 2 patches contain a small fix to avoid additional response
latency in case of request timeout being reached and reorganize the
code for better logical flow. The final patch then adds the
additional response status code checks for retires.
