Return actual queue attributes with result from sqs_queue creation/update (#1362)

* Return actual queue attributes with result

Previously this was only returning the desired queue attributes, and not even returning the QueueARN for use elsewhere.  Now it will return "results.attributes" that is retrieved with boto's get_queue_attributes().

* update return structure to reflect current SQS config; add documentation of return values

* Remove redundancy from if/else statement
