title: Issue in making Https request from Mule with TLS v1.2 and without SSL certificate verification
body: <p>I want to make a https request with a TLS v1.2.
  I found a property as follows:</p>
  
  <pre><code>&lt;tls:context name="trustallcertificate" enabledProtocols="TLSv1.2"&gt;
      &lt;tls:trust-store insecure="true" /&gt;
  &lt;/tls:context&gt;
  </code></pre>
  
  <p>But it is for <code>&lt;http:listener-config name="globalConfig" protocol="HTTPS" host="localhost" port="8443"&gt;</code></p>
  
  <p>Is there a similar configuration for a outbound request.
  I tried with '<code>&lt;spring:property name="sslType" value="TLSv1.2"/&gt;</code>'
  But following error came:</p>
  
  <blockquote>
