The essence of this commit is to help people get started with a better
indentation practice than this:

```yaml
spec:
  labels:
{{ toYaml .Values.labels | indent 4 }}
```

The previous indentation practice is harder to read. Instead this commit
introduces an indentation practice using `nindent` like this:

```yaml
spec:
  labels:
    {{- toYaml .Values.labels | nindent 4 }}
```
