Fix nova-bootstrap job labels

Similar to earlier changes [0] [1], this change ensures that the labels
for the nova-boostrap job are consistently applied under .metadata and
.spec.template.metadata.

Unfortunately, there was a conflict in the "application" label that was
unresolvable in a backwards-compatible way.

    metadata:
      labels:
        application: nova-bootstrap
    spec:
      template:
        metadata:
          labels:
            application: nova
            ...

The standard helm-toolkit labels are now applied in both places, and the
application: nova-bootstrap label is removed.
