[pve-devel] [PATCH proxmox-ve-rs 3/6] ve-config: add helper function to iterate over all nodes in all fabrics

[Stefan Hanreich <s.hanreich@proxmox.com>]

From: Gabriel Goller <g.goller@proxmox.com>

Add helper function to iterate over all nodes in all fabrics. This is
especially useful e.g. when retrieving the stats as we need to find all
the fabrics on the current node (and their node config).
