title: RestTemplate with Bearer Authorization
body: <p>Is it possible to create with RestTemplateBuilder an instance of RestTemplate with just the bearer header and token?</p>
  
  <p>I know i can use RestTemplate exchange and set inside the HttpEntity my headers but is it possible to do something like this:</p>
  
  <pre class="lang-java prettyprint-override"><code>public RestTemplate getRestTemplate(){
      RestTemplateBuilder builder = new RestTemplateBuilder();
      return builder.build().exchange().setBearerAuth("token here"); //this is not possible
  }
  </code></pre>
  
  <p>Hope you understand what i want to do.</p>
