This patch set makes manila-ui code work with Django 1.9:
- replaces deprecated django.utils.unittest with unittest
- removes {% load url from future %} lines
- replaces old-style urlpatterns with new ones
Also, since Django < 1.7 is not supported any more by upstream,
this patch removes Django 1.4 from tests and replaces it with
Django 1.9 (while it's not in upstream yet) and Django 1.10.
