Integration tests cleanup

This patch does a cleanup and fixes some nits found by reviewers
in the original patches [1], some of them are:

- import json instead of jsonutils
- use six.moves.http_client
- put common logic on clients superclass
- use "fails" to indicate negative cases
- stronger comparison in update tests
