All api server configurations should expose the ability to configure the keystone_authtoken middleware. We have created a central place to manage this via the puppet-keystone module. The resource keystone::resource::authtoken should be used to configure the keystone_authtoken sections of each of the api service configs.

https://review.openstack.org/#/c/342905/ can be used as an example of the work that needs to be handled for this. Additionally, backwards compatibility is a must.
