title: Remove quotes from Ansible variable output
body: <p>I'm using this task to add a line to a file:</p>
  
  <pre><code>lineinfile: "dest={{ ansible_env.HOME }}/{{ deploy_dir }}/config/deploy/{{ stage_name }}.rb
                insertbefore='# role-based syntax'
                line='server "'{{ ip_addr }}'", user: "'{{ user_name }}'", roles: %w{'{{ role }}'}'"
  </code></pre>
  
  <p>Which adds this line:</p>
  
  <pre><code>server '172.16.8.11', user: 'vagrant', roles: %w{'api'}
  </code></pre>
  
  <p>But I don't want the quotes around <code>api</code>. Instead I want this output:</p>
  
  <pre><code>server '172.16.8.11', user: 'vagrant', roles: %w{api}
  </code></pre>
