* fix(custom_cni): make namespace optional Keep kube-system as the default for existing manifests. An empty custom_cni_namespace omits kubectl's namespace flag so manifests spanning multiple namespaces can be applied without changing legacy behavior.

Custom CNI manifest generation
As an example we are using Cilium for testing the network_plugins/custom_cni.
To update the generated manifests to the latest version do the following:
helm repo add cilium https://helm.cilium.io/
helm repo update
helm template cilium/cilium -n kube-system -f values.yaml > cilium.yaml
The generated Cilium manifest contains resources in both the kube-system and
cilium-secrets namespaces. Configure the static manifest example without a
kubectl namespace argument:
custom_cni_manifests:
- "{{ playbook_dir }}/../tests/files/custom_cni/cilium.yaml"
custom_cni_namespace: ""
When custom_cni_namespace is empty, every namespaced resource in the
manifests should declare metadata.namespace. Otherwise, kubectl applies the
resource to the current context's default namespace.
