Support for Request/Response pattern

[brainmurphy]

When one application sends a message to another, it may be interested in receiving a reply - a two-way conversation. For example, if I send a command I might expect to receive a "success/failure" message in response.

In order to support this asynchronous request/response pattern in JustSaying, the receiving application needs to know where to send the response message to. This could probably be accomplished by using a well-defined "reply to" property on the command message indicating, for example, the SQS queue to which the response should be sent. Or perhaps we could define an SQS message attribute to convey this.

Either way, providing first-class support for this pattern in the library would be useful for clients, allowing them to implement this pattern with minimal setup.
