ID filter not consistent across all models

[jeremystretch]

Environment

• Python version: 3.6.9
• NetBox version: 2.8.2

Steps to Reproduce

1. Disable any installed plugins by commenting out the PLUGINS setting in
   configuration.py.
2. Attempt to filter the /api/circuits/providers/ endpoint by passing provider database IDs; e.g. GET /api/circuits/providers/?id=1&id=2

Expected Behavior

The API should return only the providers corresponding to the provided IDs.

Observed Behavior

The filtering is ignored.

The provider model is used only as an example here: This issues afflicts several models across the application. The legacy id__in filter was removed in #4313, however the id field was never added to certain models to replace its functionality.
