Since we already migrated fully to Python3, it's time to also remove
bits needed for Python2. One of those libs is six.

According to CNI spec kubelet expects CNI_IFNAME (the name
inside container) if sandbox is not empty.
Both python and golang implementation was done unconditionally,
IOW we can add both empty sandbox and interface name on the
host and nonempty sandbox and container's iface name.

Deploying without kuryr-daemon is deprecated since Rocky and we
announced that it will be removed in the Rocky release notes. This
commit removes all the code that allows that, updates the documentation,
DevStack plugin and gates definitions.

Seems like base class method definition is missing `params` argument
that's present in it's implementations. This commit fixes that by adding
it.

Kuryr-kubernetes declares, that supported CNI version is 0.3.0, but
it prints to output in format of version 0.2.0.
Kubernetes can't parse it.
This patch modifies CNI output according to 0.3.1, it has a little
difference with version 0.3.0, just in naming of ips field.

This commit alters the format of the annotation, set and read by
controller/CNI. Instead of a single VIF object it now holds a
dictionary, that maps interface names to VIF objects. Controller
currently only sets 'eth0' as the default VIF. The CNI is altered
accordingly to read VIFs from the mapping and add all of them to Pods
namespace.
This commit does not include any mechanism to actually request multiple
IPs/ports for a Pod, but rather lays foundation for future commits, that
would allow that.

This patch moves the cni plugins that were split between api.py,
main.py and daemon/service.py to have then in a unified path.

This commit implements basic CNI daemon service. The aim of this new
entity is to increase scalability of CNI operations by moving watching
for VIF to a separate process.
This commit:
* Introduces kuryr-daemon service
* Implements communication between CNI driver and CNI daemon using HTTP
* Consolidates watching for VIF on CNI side to a single Watcher that
looks for all the pods on the node it is running on.
* Solves bug 1731485 when running with CNI daemon.
* Enables new service in DevStack plugin
* Provides unit tests for new code.
Follow up patches will include:
- Documentation.
- Support for running in containerized mode.
To test the patch add `enable_service kuryr-daemon` to your DevStack's
local.conf file.

Without this patch, when successfully exiting the CNI runner, we'd log
something like:
2017-05-16 16:45:11.763 32397 DEBUG kuryr_kubernetes.cni.main [-] Exiting with status None run /usr/lib/python2.7/site-packages/kuryr_kubernetes/cni/main.py:96
After this change, we report the real exit status we'll give to the
kubelet:
2017-05-16 16:56:14.750 33914 DEBUG kuryr_kubernetes.cni.main [-] Exiting with status 0 run /usr/lib/python2.7/site-packages/kuryr_kubernetes/cni/main.py:96

1.As mentioned in [1], we should avoid using
six.iteritems to achieve iterators. We can
use dict.items instead, as it will return
iterators in PY3 as well. And dict.items/keys
will more readable. 2.In py2, the performance
about list should be negligible, see the link [2].

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.
