CSV upload silently ignores invalid columns

[candlerb]

NetBox version

v3.5.6

Python version

3.8

Steps to Reproduce

Go to Interface Bulk Import (/dcim/interfaces/import/)

Paste in the following:

device,name,type,wombat
nuc1,blah,virtual,flurble

(where 'nuc1' is some existing device)

Expected Behavior

Import to be rejected because of the unknown attribute/column "wombat"

Observed Behavior

The import is silently accepted.

The same applies if you try to modify an existing interface, e.g.

id,wombat
451,flurble

where 451 is an ID of an existing interface.

It's not just for interfaces: the same can be seen when creating Devices

device_role,manufacturer,device_type,status,site,wombat
Server,Unknown,Patch Panel 24,active,Test,flurble

(assuming that the given device_role, manufacturer, device_type, site are all pre-existing objects)
