@Query annotation to support query limiting

[boostchicken]

This will allow you to limit the results returned from a DynamoDB query that has a sort and range key, techincally also a Scan. I developed this to reduce cost b ased on the new OnDemand pricing.

Example:

@Query(limit = "10")
List<Blah> findFirst10ByStatusAndDateTimeBeforeOrderByDateTimeDesc(String Status, String DateTime);

The previous behavior would actually return every single result and then clip it. With this limit parameter dynamo only returns the request amount of results. This is mainly for HashAndRange. It still requires First10 and the Query annotation to work otherwise the Spring-DynamoDB will just do queries limited to 10 results until it gets them all.

A little look at how my query results return look based on this now. Also usage metrics are way down.
