[pbs-devel] [PATCH v6 proxmox-backup 10/29] api types: implement api type for `BackupGroupDeleteStats`

[Christian Ebner]

Make the `BackupGroupDeleteStats` exposable via the API by implementing
the ApiTypes trait via the api macro invocation and add an additional
field to account for the number of deleted groups.
Further, add a method to add up the statistics.
