This change allows other auth systems to test against the functests but not require them to support x-storage-token (which was deprecated before swift was even open-sourced). All other places in the code where x-storage-token is used is only to populate x-auth-token if x-auth-token doesn't already exist. Change-Id: Ie903d0f7135fc643353b74a61c14becf7dfc4d9d
