Code Issues Proposed changes

Switch to PyMemcacheCache backend

Browse Source 
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.

upgrade:
- |
Default cache backend has been changed from MemcachedCache backend to
PyMemcacheCache backend. MemcachedCache backend was deprecated in django
3.2 and was later removed in django 4.1. Note that the LOCATION option
needs to be updated in case memcached servers use IPv6, so that inet6
prefix is not included.
