Implement functionality virtually replicating deployment templates for
nfd-master and nfd-worker daemonset (nfd-master.yaml.template and
nfd-worker-daemonset.yaml.template) by adding a kustomize overlay named
"default".
We split the resources into multiple bases (rbac, master and
worker-daemonset) so that relevant parts are re-usable in
other deployment scenarios added later (e.g. "one-shot job", and
"combined daemonset").
This patch adds one component (components/common) doing the required
kustomization for the example deployment.
