    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, 201, 202, 400, 403, 404, 405, 413, 500 under
    tests/unit/api/contrib 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
