Fixes #23818 - Update fog-openstack to save OpenStack OSP 12
On fog-openstack 0.1.23, Excon expects a 200 when it creates the first key-pair on OpenStack. On recent versions, it returns a 201. There is a fix for it on fog-openstack 0.1.25, so we should update to it both in Foreman and in packaging.
