Replace the one.sh/tempfile polling script with Zabbix dependent items and XML XPath preprocessing, so history/trends are native per metric instead of shelling out on every check.

  • Add LLD discovery for hosts, VMs, datastores, networks, clusters, users, and groups, with per-resource items and triggers
  • Add per-VM state/LCM state, CPU, and memory monitoring
  • Add user/group quota monitoring
  • Add real (hypervisor-reported) CPU/RAM usage, per-host and fleet-wide, alongside OpenNebula's allocated capacity
  • Add macro-driven trigger thresholds and component/software tags on every item and trigger
  • Rework the dashboard into three pages (Overview, Host/Cluster, VMs) using gauges, SVG graphs, pie charts, and Honeycomb widgets

See CHANGELOG.md for the full list of changes.
