* policy_fixture: replace jsonutils.load() with jsonutils.loads() to
support bytes and Unicode. Use also a context manager to open the
file to fix a ResourceWarning on Python 3.
* pipelib: replace str.encode("base64") with base64.b64encode(str)
* cmd/manager.py: replace urllib.unquote() with urlparse.unquote(),
urlparse comes from "import six.moves.urllib.parse as urlparse"
* enable tests on Python 3
- test_pipelib
- test_policy
* enable also tests which already passed on Python 3:
- test_quota
- test_test_utils
