Allow queue to edit its attributes

[rhiroyuki]

When changing one of the queue properties (VisibilityTimeout in this case) and running aws:sqs:create[force], this error is raised:

Aws::SQS::Errors::QueueAlreadyExists: A queue already exists with the same name and a different value for attribute VisibilityTimeout                            

Not sure if this is possible but rather than raising an error we should update the queue property instead in this case. Or maybe sending an additional argument telling it to update.
