title: Escape dot in Helm template
body: <p>In <code>values.yaml</code> I have:</p>
  <pre><code>key1:
    key2.yaml:
      key3:
      - name
        value
      - name
        value
  </code></pre>
  <p>Inside a template, how can I get to <code>key3</code>? <code>{{ .Values.key1.key2.yaml.key3 }}</code>  does not work because <code>key2.yaml</code> in this context corresponds to</p>
  <pre><code>key1:
    key2:
      yaml:
        key3:
        ...
  </code></pre>
  <p>Escaping the <code>.</code> with <code>\</code> results in:</p>
  <pre><code>$ helm template .
  Error: parse error at (...): bad character U+005C '\'
  </code></pre>
