Lu lei 2fb98a6b82 py3:Remove six.iterXXX
1、As mentioned in [1], we should avoid using six.iteritems/keys
   achieve iterators. We can use dict.items/keys 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].
