Django 1.11 is currently the "default" version in the ports tree due its
long term support until April 2020 thus ports that are assigned to that
version will exist until then.
The following packages are required to make the upgrade of net-mgmt/netbox
to 2.5.x possible because upstream has decided to switch from Django 1.11
to Django 2.1:
* www/py-dj21-django-cors-headers
* www/py-dj21-django-debug-toolbar
* www/py-dj21-django-filter
* www/py-dj21-django-js-asset
* www/py-dj21-django-mptt
* www/py-dj21-django-tables2
* www/py-dj21-django-taggit
* www/py-dj21-django-timezone-field
* www/py-dj21-djangorestframework
* www/py-dj21-drf-yasg
Also limit the new ports to Python 3.5 and later to match the requirements
for Django 2.1 and to reduce some overhead in the building infrastructure.
