Sean Eagan b1a247e7f5 Helm 3 - Fix Job labels
If labels are not specified on a Job, kubernetes defaults them
to include the labels of their underlying Pod template. Helm 3
injects metadata into all resources [0] including a
`app.kubernetes.io/managed-by: Helm` label. Thus when kubernetes
sees a Job's labels they are no longer empty and thus do not get
defaulted to the underlying Pod template's labels. This is a
problem since Job labels are depended on by
- Armada pre-upgrade delete hooks
- Armada wait logic configurations
- kubernetes-entrypoint dependencies

Thus for each Job template this adds labels matching the
underlying Pod template to retain the same labels that were
present with Helm 2.
