[pbs-devel] [PATCH v3 proxmox-backup 2/7] client: backup writer: fix upload stats size and rate for push sync

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

Currently, the logical size of the uploaded chunks is used for size
and upload rate calculation in case of sync jobs in push direction,
leading to incorrect values of the actual transferred size and rate.

Use the compressed chunk size instead, by returning the more verbose
`UploadStats` on `upload_index_chunk_info` calls and use it's
compressed size for the transferred `bytes` of `SyncStats` instead,
being finally used to display the upload size and calculate the rate
for the push sync job.
