        Monitors Proxmox Backup Server backup groups via REST API.
        Dynamically discovers all datastores, namespaces, and backup groups.

        Setup:
          1. Deploy /usr/local/bin/pbs-backup-monitor on the PBS host
          2. Add /etc/zabbix/zabbix_agent2.d/pbs.conf on the PBS host
          3. Restart zabbix-agent2 on the PBS host
          4. Set host macro {$PBS.MAX.AGE.SECONDS} as needed

        Context macro key format: "{datastore}:{namespace}:{type}:{id}"
          Root namespace example:  "zfs-vol-02::vm:1001"
          Sub-namespace example:   "zfs-vol-02:cluster-a:vm:1001"
