horizon/openstack_dashboard/settings.py
Radomir Dopieralski caa99b2010 Switch to PyMemcacheCache backend 
The new library is already supported in django 3.2 and gives us better
support for IPv6 addresses and encrypted connections.

Also, the same library is being used by all other OpenStack projects.

Depends-on: https://review.opendev.org/c/openstack/devstack/+/898302
Closes-Bug: #2039225
