Chart fails when nexus.extraLabels is used

[hWorblehat]

Adding a nexus.extraLabels mapping causes templating to fail with the following message:

Error: YAML parse error on nexus-repository-manager/templates/deployment.yaml: error converting YAML to JSON: yaml: line 11: mapping values are not allowed in this context

Looking at the output with --debug, it appears the the first entry in the extraLabels map is indented too far, and this is causing the problem.

The template files seem to use the syntax:

  {{- if .Values.nexus.extraLabels }}
    {{- with .Values.nexus.extraLabels }}
      {{ toYaml . | indent 4 }}
    {{- end }}
  {{- end }}

I believe switching from indent to nindent should fix the issue.
