https://review.openstack.org/#/c/255599/ implemented a keystone-manage
bootstrap command as an alternative to using an admin token when
bootstrapping the keystone service. Admin tokens have been deprecated
as of Mitaka and will be removed in Ocata.
The use of this command replaces tasks to create the admin user, its
password, role, and project and the keystone service endpoints.
The keystone_auth_admin_token variable has been removed and its use in
any tasks against the keystone library have been replaced with login
credentials for the admin user.
The functional test has been updated to use the current head of
stable/mitaka and master for keystone and requirements respectively. The
policy and api-paste files have also been updated from the head of
keystone stable/mitaka.
This change will require updates to make use of the same SHAs in the
integrated openstack-ansible repo and in a majority of the OpenStack
service roles' tests.
