podAnnotations - did not find expected key

[alanorther]

Issue:

Adding podAnnotations value to nsqlookupd, nsqadmin, or nsqd in the values file gives the following error or similar:
helm upgrade --install -f nsq-values.yaml nsq nsqio/nsq
Error: UPGRADE FAILED: YAML parse error on nsq/templates/nsqadmin-deployment.yaml: error converting YAML to JSON: yaml: line 19: did not find expected key

Example Values File Input:

  podAnnotations:
    Test_Annotations: "testing"

Fix to template files:

    metadata:
      {{- with .Values.nsqlookupd.podAnnotations }}
+     annotations:
        {{- toYaml . | nindent 8 }}
      {{- end }}

Files that require update:

templates/nsqadmin-deployment.yaml
templates/nsqd-statefulset.yaml
templates/nsqlookupd-statefulset.yaml

Hmm, it's been that way from the first commit in this repo. Maybe no-one ever used podAnnotations. Though maybe you could theoretically do something like:

podAnnotations:
  annotations:
    myrealm: blue

Anyway, would you like to open a Pull Request with your suggested fix?
