Subject: [PATCH 02/28] Update django from 1.11.8 to 2.0

- Refactor django.core.urlresolvers module import to django.urls. Resolves: The django.core.urlresolvers module is removed in favor of its new location, django.urls.

- Add an app namespace to urls in user app. Resolves: Support for setting a URL instance namespace without an application namespace is removed.
