Allow custom annotations and labels on Pods

[AndresPineros]

The only way to monitor what the descheduler does to the cluster is by checking the logs. For most logging tools for Kubernetes (for example Kibana), labels and annotations are critical to filter information.

Maybe something like:

...
...
...
spec:
  schedule: "{{ .Values.schedule }}"
  jobTemplate:
    metadata:
      labels:
{{ if .Values.labels }}{{ toYaml .Values.labels | indent 8 }}{{end}}
        app: {{ template "descheduler.name" . }}
        release: {{ .Release.Name }}
      annotations:
{{ if .Values.annotations }}{{ toYaml .Values.annotations | indent 8 }}{{end}}
        scheduler.alpha.kubernetes.io/critical-pod: "true"
        checksum/config: {{ include (print $.Template.BasePath "/configmap.yaml") . | sha256sum }}
    spec:
      template:
        metadata:
          labels:
{{ if .Values.labels }}{{ toYaml .Values.labels | indent 12 }}{{end}}
            app: {{ template "descheduler.name" . }}
            release: {{ .Release.Name }}
          annotations:
{{ if .Values.annotations }}{{ toYaml .Values.annotations | indent 12 }}{{end}}
            scheduler.alpha.kubernetes.io/critical-pod: "true"
            checksum/config: {{ include (print $.Template.BasePath "/configmap.yaml") . | sha256sum }}
        spec:
...
...
...
