Please make metadata.annotations as part of the deployment.yaml to get configured via values

[VF-mbrauer]

In order to configure some more annotations for the Deployment under metadata.annotations it would be good to get it configured via value file with

annotations:
  scheduler.alpha.kubernetes.io/node-selector: machine-id =12345

Is this related to #142

Wondering whether this is talking about top-level deployment annotations, or pod-spec annotations (which the PR seems to address).
