The Kubernetes Kubenet CNI bridge was getting the default networkd configuration applied which tries to attach an IP address through DHCP. This meant that the interface was stuck in this "configuring" state by networkd and this is also a potential source of disruption as reported in similar cases. Set the cbr0 interface to be excluded from networkd (unmanaged) because it is set up manually by kubenet and not through DHCP.
