[pbs-devel] [PATCH v3 proxmox-backup 30/33] api types: implement api type for `BackupGroupDeleteStats`

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

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.

changes since version 2:
- rename `unremoved_protected` private field to more fitting
  `protected_snapshots` to be in line with patch 29.
