Lots of thanks to @btriller for the majority of the work on this PR
Previous PR for this: #1020

New Behavior

Allows assigning a component to an inventory item

Contrast to Current Behavior

We cannot assign a component to an inventory item

Discussion: Benefits and Drawbacks

Benefit: Users can optionally assign the component to an inventory_item.
Drawbacks:

• It is not possible to update a created item with a component as we use components in the ALLOWED_QUERY_PARAMS
  ex: If you create item1 with no components and try again with components it will create a new inventory item.

Proposed Release Note Entry

Allow the assignment of components to inventory items

I believe this carries over from this PR #1066 (comment)

Sorry for the last minute pushes, noticed the name weren't right for the tests.

The CI failure appears to be unrelated to your change. It appears something got merged that broke the tests. Investigating.....

@sc68cal When I looked into it, the issue seems to be from netbox itself when they changed the way available ips are structured. netbox-community/netbox#13746
