Move Queues out of Python

[xanderdunn]

I've created a FIFO queue api-ml-production.fifo. It's guaranteed to deliver each message only once. Each message has hidden visibility for 2 minutes after it's been received by a consumer. This means we could have many submission-criteria instances running and if one of them were to fail and not mark the message as completed within 2 minutes, the message would become available in the queue for another consumer to receive. This wait time can be modified.

boto library to interact with it.

api-tournament should put it into the queue and then submission-criteria should be restructured so that it isn't a server at all, but simply checks the FIFO queue in a loop.
