[PATCH manager v3 01/18] api/pvestatd: broadcast and expose non-x86 host architecture

[Dominik Csapak <d.csapak@proxmox.com>]

in case a nodes runs a non-x86 kernel, broadcast that info into the
'static-info' hash to pmxcfs (once). Use that info to add an
'architecture' property to /cluster/resources.

x86 nodes won't return a value here.
