    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 202, 204, 300 and 412 under api/v3 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
