Proposed functionality

Currently, "brief" mode REST API responses do not include an object's description:

# GET /api/dcim/sites/1/?brief=true
{
    "id": 1,
    "url": "http://netbox:8000/api/dcim/sites/1/",
    "display": "DM-NYC",
    "name": "DM-NYC",
    "slug": "dm-nyc"
}

This proposal is to include the description field in this output, where applicable.

Use case

Following #13283, the description field can be included on dynamically-populated dropdown fields to convey additional context about each object. It is also likely useful in many other scenarios, and its inclusion imposes no significant performance penalty.
