[pve-devel] [PATCH v2 ha-manager 01/15] env: add get_static_node_stats() method

[Fiona Ebner <f.ebner@proxmox.com>]

to be used for static resource scheduling. In the simulation
environment, the information can be added in hardware_status.

Signed-off-by: Fiona Ebner <f.ebner@proxmox.com>

Changes from v1:
    * Properly add it to the simulation environment.
