title: reuse complex spring-fox swagger annotation
body: <p>I am using the spring-fox2 <code>@ApiImplicitParam</code> annotation to make the swagger-ui show a box for including an Authorization header with a request:</p>
  
  <pre><code>@ApiImplicitParams({
          @ApiImplicitParam(
                  name="Authorization",
                  value="authorization header containing the bearer token",
                  paramType = "header"
          )
  })
  public void someControllerMethod() {
      ...
  }
  </code></pre>
  
  <p>This works fine, but I need this authorization header for each method in the controller. Copying and pasting this is code smell. Can I define some kind of shortcut annotation for this? Is there a different way of telling swagger-ui to create an input field for the authorization header?</p>
  
  <p>Thanks!</p>
