Subject: [PATCH] [htk] Jobs; put labels only in the template spec

This is an update to address a behavior change introduced with
0ae8f4d21ac2a091f1612e50f4786da5065d4398.

Job labels if empty/unspecified are taken from the template.  If (any)
labels are specified on the job we do not get this behavior.

Specifically if we *apply*:

    apiVersion: batch/v1
    kind: Job
    metadata:
      # no "labels:" here
      name: placement-db-init
      namespace: openstack
    spec:
      template:
        metadata:
          labels:
            application: placement
            component: db-init
            release_group: placement
        spec:
          containers:
          # do stuffs

then *query* we see:

    apiVersion: batch/v1
    kind: Job
    metadata:
      # k8s did this for us!
      labels:
        application: placement
        component: db-init
        job-name: placement-db-init
        release_group: placement
      name: placement-db-init
      namespace: openstack
    spec:
      template:
        metadata:
          labels:
            application: placement
            component: db-init
            release_group: placement
        spec:
          containers:
          # do stuffs

The aforementioned change causes objects we apply and query to look
like:

    apiVersion: batch/v1
    kind: Job
    metadata:
      # k8s did this for us!
      labels:
        application: placement
        # nothing else!
      name: placement-db-init
      namespace: openstack
    spec:
      template:
        metadata:
          labels:
            application: placement
            component: db-init
            release_group: placement
        spec:
          containers:
          # do stuffs

Current users rely on this behavior and deployment systems use job
labels for synchronization, those labels being only specified in the
template and propagating to the job.

This change preserves functionality added recently and restores the
previous behavior.

The explicit "application" label is no longer needed as the
helm-toolkit.snippets.kubernetes_metadata_labels macro provides it.
