Made numerous changes to ensure compatibility with HP Public Cloud and Helion/Private Cloud. CDN, ObjectStorage, StreamWrapper, StreamWrapperFS, IdentityServices, and TestCase were affected. Primary changes include the following: 1. Tests using account ID and secret key have been removed. 2. Default regions removed from ObjectStorage class. 3. User warnings are sent when CDN is not enabled since it's only available in HP Public Cloud. 4. TestCase has been modified to be more robust and handle cases where a previous test run may have failed in unexpected ways.
