Reviewers

Django 3.1 is currently in RC, so it will be out before long. To
prepare, we're adding support for 3.1.

There isn't much in the way of changes here, just a new concrete_model
key in Model._meta that had to be set for our mock models, removal of
the legacy FieldDoesNotExist compatibility import (this moved from
django.db.models.fields to django.core.exceptions in Django 1.8),
and some small changes to our tests to handle some minor SQL schema
changes (just bringing back a missing space before DESC that's been
gone since Django 2.0).

Unit tests pass for all supported versions of Django on all databases.

Add early support for Django 3.1.
Django 3.1 is currently in RC, so it will be out before long. To prepare, we're adding support for 3.1. There isn't much in the way of changes here, just a new `concrete_model` key in `Model._meta` that had to be set for our mock models, removal of the legacy `FieldDoesNotExist` compatibility import (this moved from `django.db.models.fields` to `django.core.exceptions` in Django 1.8), and some small changes to our tests to handle some minor SQL schema changes (just bringing back a missing space before `DESC` that's been gone since Django 2.0).
