This patch implements external monitoring of the Kube-OVN cluster. A new reconciler timed to run its reconcile loop at a fixed interval execs into the ovn-central pods and collects their cluster info. If the members' opinions about the cluster disagree, an alert is raised. Other issues with the distributed consensus are also highlighted. ```release-note [kubeovn,cozystack-controller] Implement the KubeOVN plunger, an external monitoring agent for the ovn-central cluster. ``` Signed-off-by: Timofei Larkin <lllamnyp@gmail.com>
