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, 204, 400, 403, 404, 405 and 413 under
tests/functional, tests/tempest and tests/unit/api are replaced with
symbolic constants from six.moves.http_client thus improves code
readability. More patches will be submitted to address other status
codes.
