Replace iteritems with items
Replace iterkeys with keys
Replace itervalues with values
Special Note:
In Python 2 those are copies of the elements.
In Python3 those are references to the dictionary elements.
The openstack python2to3 documents suggests wrapping the calls with
a list if the dict is expected to change while iterating.
nfv_scenario_tests (non guest) all pass.
