Be able to configure multiple annotations to add to a pod depending on pod labels

[santinoncs]

Old config:

  config: |
    metadata:
      annotations:
        cluster-autoscaler.kubernetes.io/safe-to-evict: "true"

new config:

config:
  default:
    metadata:
      annotations:
        cluster-autoscaler.kubernetes.io/safe-to-evict: "true"
  some-label-value:
    metadata:
      annotations:
        example.com/some-annotation: "true"

It will apply the example.com/some-annotation: "true" annotation to pods with the annotation-type label set to some-label-value.

Could you explain why do we need this?

Could you explain why do we need this?

Maybe in some cases we want to include another annotation depending on the labels.
For instance redis cluster leader-0 needs this annotation

cluster-autoscaler.kubernetes.io/safe-to-evict: "false"

as we don't want the cluster autoscaler to evict it.
