API Bug when posting cluster create in Job board

[Davide Agnello]

The timestamp error patch (https://review.openstack.org/#/c/169128/12) introduced a problem with how API Cluster Objects are built in the constructer.

before change:
setattr(self, k, kwargs.get(k, wtypes.Unset))

after change:
if kwargs.get(k) is None:
  setattr(self, k, wtypes.Unset)
else:
  setattr(self, k, kwargs.get(k))

The reason for this change was not to show 'None' fields in cluster response bodies returned from the API. This also caused an issue when the create cluster job is posted to task flow.

    Resolving Removing Empty fields from API responses

    * Returning empty fields set to Nonw for unset fields will cause
      problems on for Python-cueclient. Specifically when updated_at
      field is returned as None and Python-cueclient tries to create
      a datetime object from it.
