Flame needed pemanent adjustments to mathe the changes in the
python-openstackclients. We now use openstacksdk or shade which will
handle themselves the compatibility.
We also made flame modular so that any-one can add features by
implementing there own flame managers and adding their modules to
the `openstack_flame` entry point.
This new flame version is also fully compatible with python 3.
