*/py-dj32-*: Deprecate/Set to expire

* The port net-mgmt/netbox was switched from Django 3.2 to Django 4.0
  in d96a960530f3c20a9edd7837583ff7bec092566f.

  Since then all the */py-dj32-* ports have no more consumers and all
  the other Django ports have been switched to Django 3.2 in the last
  few weeks. [1] Hence the py-dj32-* ports are redundant now.

  Mark the py-dj32-* as deprecated and set an expiration to the end of
  2022Q2 to get a clean 2022Q3 branch.

devel/py-dj32-django-rq: Update TEST_DEPENDS after
51c8c9bdc20f2c5166fa98f9c14b1000a0f199d7

*: Create Django 3.2 ports for net-mgmt/netbox

* Django 2.2 is currently the "default" version in the ports tree due
  its long term support until April 2022.  Thus ports that are assigned
  to that version will exist until then.

  The following ports are required to make the upgrade of
  net-mgmt/netbox to the 2.11 release possible because it requires
  Django 3.2.  All of the ports listed below were created on the basis
  of their respective original ports:

  - devel/py-dj32-django-rq
  - www/py-dj32-django-auth-ldap
  - www/py-dj32-django-cacheops (updated to a newer release)
  - www/py-dj32-django-cors-headers
