			1. As mentioned in [1], we should avoid using six.iteritems to achieve iterators. We can use dict.items instead, as it will return iterators in PY3 as well. And dict.items/keys will more readable. 2. In py2, the performance about list should be negligible, see the link [2]. [1] https://wiki.openstack.org/wiki/Python3 [2] http://lists.openstack.org/pipermail/openstack-dev/2015-June/066391.html Co-Authored-By: Akihiro Motoki <amotoki@gmail.com> Change-Id: I4b9edb326444264c0f6c4ad281acaac356a07e85 Implements: blueprint replace-iteritems-with-items
