title: Access-control-allow-origin on aws javascript sdk getSignedUrl operation?
body: <p>Is it possible to set access-control-allow-origin on getSignedUrl operation for a S3 object? 
  I have been looking out for a list of available params from the aws documentation but it's unclear.</p>
  
  <p>Update: 
  Suppose I have an object "test-file.jpg" in a bucket named "test-bucket". There is no CORS policy set on the bucket. 
  The signed URL created by the getSignedUrl method throws 'no access-control-allow-origin header present' not allowed error in the browser.</p>
  
  <pre><code>var s3 = new aws.S3({'signatureVersion': 'v4'});
  var options = {
      Bucket:"test-bucket",
      Key:"test-file.jpg",
      Expires:120
  }
  var signedUrl = s3.getSignedUrl('getObject', options);
  </code></pre>
  
  <p>Is there an option to set the <code>access-control-allow-origin : *</code> in the above function call?</p>
