Overview

Handler for listing and describing snapshots.

Uses --vmid flag (repeatable) for VM/CT filtering and --node for node filtering. Without --vmid, operates cluster-wide.

Examples:

List snapshots for specific VMs

handler.list(args: [], vmid: ["100", "101"])

List all snapshots cluster-wide

handler.list(args: [])
