239bed09a9
This change adds tests cases for the default roles keystone supports at install time. It also modifies the policies for the credentials API to be more self-service by properly checking for various scopes. Closes-Bug: 1788415 Partial-Bug: 968696 Change-Id: Ifedb7798c96930b6cc0f91159a14a21ac4b02f9f
