    Use public endpoint for [keystone_authtoken] www_authenticate_uri

    According to the parameter description, www_authenticate_uri should be
    complete public Identity endpoint, which is accessible by all end
    users.
    This change replaces internal endpoint by public endpoint to meet that
    requirement.
