Enable python34 tests for nova/tests/unit/scheduler/test*.py

nova/pci/stats.py:
  need to specify a key parameter which is a function that returns
  a sorting key. since the original intention with pool_cmp was to
  sort by number of items in each pool, we just use key parameter
  with a lambda
nova/scheduler/filters/trusted_filter.py
nova/scheduler/host_manager.py
  needed list() so we could delete stuff inside the loop in py3
nova/tests/unit/scheduler/test_filter_scheduler.py
  needed the import of test as some tests were failing in py3,
  added noqa as test is not explicitly referenced within the
  module
nova/tests/unit/scheduler/test_scheduler_options.py
  need BytesIO for py3, StringIO will fail in many tests
nova/tests/unit/scheduler/test_scheduler_utils.py
  message is not available in py3, so we need to adjust
  use test.nested already added in a previous commit
nova/test.py
  if we have a key which is a list, treat it just like a set
nova/utils.py
  use reduce from six and explicitly typcast version_int as
  an integer
