Devstack was setting up a separate directory and copying
http/keystone.py into it for the admin and public endpoints.
Keystone now defines wsgi_scripts entrypoints so that
keystone-wsgi-admin and keystone-wsgi-public are created on
install so devstack can reference these files instead.
See http://httpd.apache.org/docs/2.4/upgrading.html#access for
the apache docs with examples for the Allow|Deny/Require
directives.
