Figure out strategy to use DynamoDBMapper Transactions in a Spring way

[boostchicken]

https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBMapper.Transactions.html

Support has been added, I went ahead and did a couple test builds but they don't work like traditional transactions. I basically just added code to the DynamoOperations interface and used it.

You may notice that each type of Write has different options, you can work across multiple Objects with a single Transaction, all good stuff, however you need to have already loaded an object.

Writing a transaction manager for this would be..... difficult to say the least and would require a lot of thought.

Just opening here for discussion.

Any updates on this?
