[pbs-devel] [PATCH v3 proxmox-backup 02/33] server: sync: move sync related stats to common module

Thu Sep 12 16:32:51 CEST 2024
Move and rename the `PullStats` to `SyncStats` as well as moving the
`RemovedVanishedStats` to make them reusable for sync operations in
push direction as well as pull direction.
