Replace any read only attributes with admin only attributes

[kalsky]

When setting an attribute to read-only, you assume that this value will only be filled by an auto-load process.
So if you use the resource in other ways, you won't be able to update the attribute values via the UI/API even as an admin.

I think we should replace the read-only property on all of these attributes with an Admin Only rule.

Another option is to allow admins to update these read-only attributes via the UI/API

Attributes such as:

1. Location (which should not be read-only anyway, since the location might change and auto-load does not necessarily knows how to fill this value).
2. Model
3. Vendor
   etc.

btw, it's relevant not only to the networking standard

Good idea!
