Ilya Chukhnakov d68a97fe47 K8s and Neutron clients support
Adds basic K8s client implementation and CONF-based singletons for
both Neutron and K8s clients.

The K8s client added by this patch should be considered a temporary
solution that only implements the necessary parts to let us move
forward with kuryr-kubernetes. Eventually it will be replaced by either
[1] or [2].

The problem with [1] is that it does not yet support the streaming API
that we need for WATCH. And [2] is outside of the OSt umbrella, so [1]
is preferred over [2] unless [2] makes it into global-requirements.txt.

[1] https://github.com/openstack/python-k8sclient
[2] https://pypi.python.org/pypi/pykube

NOTE: Removed py3-related code from config and top-level __init__.
      How to properly deal with that code is TBD.
