Currently nested containers can only be run by using trunk support and
vlan based interfaces. This patch introduces the additional option of
MACVLAN slave interfaces for pods running in VMs.
This patch includes both a new VIF driver on the controller side and the
binding driver for the CNI plugin.

In order to better organize nested drivers (VLAN and MACVLAN),
refactor the class hierachy of VIF drivers, providing better locations
for shared code. In particular:
- add an additional abstract class named NestedPodVIFDriver for nested
drivers to share common code, to accomodate the upcoming MACVLAN
driver
- rename GenericPodVIFDriver to NeutronPodVIFDriver (all the drivers are
Neutron specific)
This change is part of the MACVLAN based pod-in-VM spec and should be
applied before any following MACVLAN related patches.

This patch provides an experimental CNI driver. It's primary purpose
is to enable development of other components (e.g. functional tests,
service/LBaaSv2 support). It is expected to be replaced with daemon
to configure VIF and connect it to the pods and a small lightweight
client to serve as CNI driver called by Kubernetes.
NOTE: unit tests are not provided as part of this patch as it is yet
unclear what parts of it will be reused in daemon-based
implementation.

This patch introduces a driver that manages normal Neutron ports to
provide VIFs for Kubernetes Pods.

This patch introduces Port-to-VIF translation to 'os_vif_util' and
implements a translator that supports hybrid OpenVSwitch plugging
case.

This patch adds the Retry handler that can be used as part of the
event handling pipeline to retry failed handlers.

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.

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