Enable receiving messages from different message groups in the same Batch for FIFO queues

[tomazfernandes]

See #1020

For this we need to add a ContainerOptions to use in the FifoSqsComponentFactory to determine the proper Sink composition.

Hello @tomazfernandes ,

From what I've seen and in relation to your messages, I think we should add an option in SqsContainerOptions to not use the MessageGroupingSinkAdapter but another one that doesn't group by message group.

Is that right? If yes, I can do it !
Thanks !

Hey @alexisgra, yup, that sounds about right!

Go for it, I'll be happy to look at the PR.

Hi @tomazfernandes,
Thanks for your answer!
I'm currently working on the PR. I was wondering if I should expose a property in the @SqsListener annotation? Or just in the factory?
From what I understand from #1020, the use case may seem rather edgy. Moreover, the property only makes sense for FIFO queues with a BATCH listener.

For now, I've added a boolean messageGrouping field to the SQSContainerOptions, which defaults to true and is used in the FifoSqsComponentFactory to choose the right Sink composition.

Thanks for your help !
