[pbs-devel] [PATCH proxmox] s3-client: drop unused optional object list v2 response fields

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

The ListObjectsV2 Response contains fields as bucket name, number of
keys, number of max keys of the response and prefix of the response
keys [0]. Since the AWS S3 API reference documentation does not
explicitly mention these fields as required, they are to be
considered optional and because they are currently not used other
than for response deserialization which will fail if missing, drop
these fields for now.
