Bug Description
== Abstract ==
I'm profiling Keystone using OSprofiler tool and the appropriate Keystone+OSprofiler integration changes - https:/
== Expected ==
The local context cache added during Mitaka should cache key-value pairs per every keystone request and grab cached value from it where possible in memoize instead of hitting to Memcache.
== Observed ==
During the nova-boot request keystone API is hit 3 times including all python clients work. If we'll take a look, for instance, on the get_domain function, it's called twice per one API call, and both times it's going to the Memcache without local cache usage.
Memcache points can appear in the trace only if memcache is *really* used, not just try to grab value from it. Also /opt/stack/
