Set a few repo-copied py-dj22- ports to expire
* These ports were already set as DEPRECATED some time ago and now have no
consumers left as those have been switched back to the original ports.
Assign some ports I maintain from Django 1.11 to Django 2.2
Django 1.11 is End-of-Life since April 2020 thus switch the following ports
to Django 2.2 (which has LTS support until April 2022):
* www/py-django-auth-ldap
* www/py-django-cacheops
* www/py-django-filter
* www/py-django-prometheus
Adjust the required Python version as Django 2.2 needs at least Python 3.5+
and bump the PORTREVISION for package change.
Mark the related py-dj22-* port variants as DEPRECATED because they're
obsolete now. Don't set an expiration date yet as they're still used by
some consumers and a few more Django 1.11 ports need to be assigned to
Django 2.2 first.
net-mgmt/netbox: Update to 2.5.12 and switch to Django 2.2
Upstream decided to switch from Django 2.1 to the 2.2 LTS release to fix a
rather annoying bug that generated intermittent errors when objects were
deleted/manipulated.
Therefore the same procedure must be done in almost the same way as in
r492690 to make NetBox compatible with Django 2.2 in the ports tree.
That means to repocopy the required Django 1.11 ports, assign them to
Django 2.2, limit them to Python 3.5+ and update all related
CONFLICTS_INSTALL entries accordingly:
* www/py-dj22-django-cors-headers [1]
* www/py-dj22-django-debug-toolbar
