Offer additional labels & annotations for deployments

[mcmarkj]

In some use-cases, labels and annotations are used for enhanced monitoring, Prometheus scraping etc.

So this adds 4 new values.

Deployment Annotation & Labels -i.e. for the deployment resource itself Pod Annotation & Labels - i.e. added to the template and these are passed down to the pod created by the deployment.

An example values.yaml:

  nodeSelector: {}
  annotations: {}
  labels: {}
  podAnnotations:
    prometheus.io/port: "8080"
    prometheus.io/scrape: "true"
  podLabels: {}
