Expose send to queue options

[bill-kerr]

This PR exposes the SendMessagesOptions config object to the method returned by generateQueueSender. This was a previous feature of lambda handlers, but looks to have been left off in this recent version.

We will now be able to do something like:

Queues.sendEmail(messages, { randomDelay: 100 });
