This sucks in the git history for both projects, then moves their files
in place. It should not introduce any behavior changes to any of the
existing openstacksdk code, nor to openstack.config and openstack.cloud
- other than the name change.

TODO(shade) comments have been left indicating places where further
integration work should be done.

It should not be assumed that these are the final places for either to
live. This is just about getting them in-tree so we can work with them.

The enforcer code for reasons surpassing understanding does not work
with python setup.py build_sphinx but it does work with sphinx-build
(what?) For now turn it off. We can turn it back on once the build
sphinx job is migrated to the new PTI.
