    """Retry an HTTP request with linear backoff.  Returns the response if
    the status code is < 400 or waits (try * initial_interval) seconds and
    retries (up to tries times) if it
    is not.

    Parameters
    ----------
    method: `str`
        Method: `GET`, `PUT`, or `POST`
    url: `str`
        URL of HTTP request
    headers: `dict`
        HTTP headers to supply.
    payload: `dict`
        Payload for request; passed as parameters to `GET`, JSON message
        body for `PUT`/`POST`.
    auth: `tuple`
        Authentication tuple for Basic/Digest/Custom HTTP Auth.
    tries: `int`
        Number of attempts to make.  Defaults to `10`.
    initial_interval: `int`
        Interval between first and second try, and amount of time added
        before each successive attempt is made.  Defaults to `5`.
    callback : callable
        A callable (function) object that is called each time a retry is
        needed. The callable has a keyword argument signature:

        - ``n``: number of tries completed (integer).
        - ``remaining``: number of tries remaining (integer).
        - ``status``: HTTP status of the previous call.
        - ``content``: body content of the previous call.

    Returns
    -------
    :class:`requests.Response`
        The final HTTP Response received.

    Raises
    ------
    :class:`apikit.BackendError`
        The `status_code` will be `500`, and the reason `Internal Server
        Error`.  Its `content` will be diagnostic of the last response
        received.
