Michał Dulko 2f65d993f3 CNI split - introducing CNI daemon ...

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.
