added additionalPodLabels

[tehlers320]

Some orgs need labels for cost analysis or other reasons. This is usually something only done on the pods. https://github.com/joe-elliott/cert-exporter/issues/120

Before:

  template:
    metadata:
      labels:
        app.kubernetes.io/name: cert-exporter
        app.kubernetes.io/instance: release-name
        cert-exporter.io/type: deployment
      annotations:
        {}
    spec:

After (with label1/2 set to test):

   template:
    metadata:
      labels:
        app.kubernetes.io/name: cert-exporter
        app.kubernetes.io/instance: release-name
        cert-exporter.io/type: deployment
        label1: test
        label2: test
      annotations:
        {}
