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. Change-Id: Ib4eb410eaf9725c296fcdddd8857eb24b8929915 Partially-Implements: blueprint kuryr-k8s-integration
