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. Partial-Bug: 1731485 Co-Authored-By: Janonymous <janonymous.codevulture@gmail.com> Implements: blueprint cni-split-exec-daemon Change-Id: I1bd6406dacab0735a94474e146645c63d933be16
