Ability to set fields as null

[OliElli]

Diode version

v1.7.1

Feature type

New ingestion entity type or new field of existing entity type

Proposed feature or enhancement

I would like a way to set an attribute that currently has a value to null. Currently Diode only supports the addition of attributes. If a particular attribute is set to null, Diode interprets this as ignoring that particular attribute if it exists.

Use case

It would allow continual updating of Netbox inventory, rather than just blindly adding things only.

Further to this, I would also like to be able to delete items outright
