Public bug reported:

== Abstract ==

I'm profiling Keystone using OSprofiler tool and the appropriate
Keystone+OSprofiler integration changes -
https://review.openstack.org/#/q/status:open+project:openstack/keystone+branch:master+topic
:osprofiler-support-in-keystone - currently on review. The idea was to
analyse how does Keystone use DB/Cache layers.

== Expected vs Observed==

I'm turning off cache via setting

[cache]
enabled = False

I'm expecting all data to be fetched from DB in this case, but I still
see gets from Memcache. I mean, *real* gets, not just tries to grab
values, but real operations happening with values got from memcache here
