    Remove "no auth token" debug log

    When things go badly and we turn on debug logs, we start seeing this
    message about a missing auth token for every auth request. To the
    untrained eye, it looks like the culprit when you are debugging auth
    problems. In reality, it usually just means the initial POST
    /auth/tokens request was sent, which does not include the X-Auth-Token
    header. This log adds more confusion than clarify, so this patch removes
    itin favor of a code comment.
