[pve-devel] [PATCH ha-manager 09/18] rules: node affinity: decouple get_node_affinity helper from Usage class

[Daniel Kral]

This is done in preparation of the next patch, which moves some of the
logic of get_node_affinity(...) in the HA rule translaton stage.

Signed-off-by: Daniel Kral <d.k...@proxmox.com>

This will also become useful for another feature enhancement, which will
bring migration blockers to node affinity rules as well.
