Django 2.0 support

Replace django.core.urlresolves with django.urls

(In Django 2.0) The django.core.urlresolvers module is removed
in favor of its new location, django.urls.
It was deprecated in Django 1.10:
https://docs.djangoproject.com/en/2.0/releases/1.10/#id3

The arguments of include() has been changed in Django 1.9
and the older style was dropped in Django 2.0.
https://docs.djangoproject.com/en/2.0/releases/1.9/#passing-a-3-tuple-or-an-app-name-to-include

Add py35dj20 job to test Django 2.0 integration.
Also drops older Django unit tests from tox.ini
as horizon dropped Django <=1.10 support in Rocky.

Depends-On: https://review.openstack.org/#/c/571061/
