yes the idea was that existing roles don't get that privilege, but
i did not really find a way to add the privilige and not give it to the 
administrator role

and yes putting it in the admin bucket would mean that pveadmin gets it too

Modify is fine by me, i didn't choose it because we don't actually 
'modify' the hardware, but yes we modify the hardware configuration

putting the use in the user bracket has the side effect that
there would be a 'PVEHardwareAdmin' and 'PVEHardwareUser' role
with the same privileges, which i did find weird to have

this way we only get the PVEHardwareAdmin that can use/see the
devices

if there is a way to only have 'user' role without the admin one
please do tell ;)
