    Extracted HTTP response codes to constants

    There are several places in the source code where HTTP response
    codes are used as numeric values.

    Status codes 200, 202, 300, 400, 401, 403, 404, 405, 500 and 503 under
    tests/unit/volume/drivers are replaced with symbolic constants from
    six.moves.http_client thus improves code readability. More patches will
    be submitted to address other status codes.

    Partial-Bug: #1520159
