Switch keystone to dogpile.cache.memcached backend
memcache_pool is there to keep a limited number of thread-associated
connections open rather than a connection for every thread. If you
don't have a huge number of threads it doesn't offer anything.
Keystone is an example of a service where memcache_pool doesn't
improve things -- eventlet isn't supported anymore and more threads
is not useful due to GIL.
As such, keystone cache backend is changed to dogpile.cache.memcached.
See https://review.openstack.org/357407 for the oslo.cache help text
change.
