Ability to Filter on items with No Tags assigned, using "None"

[jonzey0]

NetBox version

v4.4.0

Feature type

Change to existing functionality

Proposed functionality

Currently in various Filter views, it is possible to search for devices, modules, cables unassigned to a Tenant, Rack, Region etc using "None" as a selection option.

I'm proposing that "None" is also made an option in the Tags field much like it already is in other fields. Essentially enables a filter specific for devices with no tags applied at all.

Use case

Gives an additional function to filtering in NetBox.

For example, I may initially setup a large environment where some devices aren't tagged. Later on I want to find which ones aren't tagged to assess whether tagging is necessary. These may be across multiple device types, racks, locations so having "None" as a filter for tagging enables me to just look at those specific devices which have no tags applied at all.

Database changes

Suspect no DB Changes Required

The filter for this already exists (e.g. GET /api/dcim/sites/?tag=null); only the addition of a "None" option to the filter options in the UI appears to be needed.
