The copy keystone.py is very outdated, and doesn't work at all
with the Juno release keystone. This patch takes the latest
keystone.py from keystone (keystone/httpd/keystone.py), where the
latest commit on the file is 0b676730347c76c7f64a67c1ad0135663e99c4fc
and replaces puppet-keystone/files/httpd/keystone.py with it.
Testing done: Tested with basic Keystone-Nova-Glance-Neutron setup
on the stable/juno branch. Keystone running on Apache with SSL
endpoints enabled.
