zhurong 87f1b5b658 Django 2.0 support and fix lower-constraints tox env
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

Add py35dj20 job to test Django 2.0 integration.
And update the lower-constraints.
