[pbs-devel] [PATCH proxmox 2/3] s3 client: refactor error response body into dedicated helper

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

Places body utf8 encoding and logging into a common place instead
of having it scattered over various places in the response status
checks.

No functional changes intended.
