Add version labels to release manifest items (#75)

Add component/version labels to each resource in the manifest. If run
locally the labels will be:

  app.kubernetes.io/component: lustre-csi-driver
  app.kubernetes.io/version: <git-version-gen>

If run from nnf-deploy's "make manifests" the labels will be:

  app.kubernetes.io/component: lustre-csi-driver
  app.kubernetes.io/version: <lustre-csi-driver's git-version-gen>
  app.kubernetes.io/part-of: nnf
  app.kubernetes.io/nnf-version: <nnf-deploy's git-version-gen>
