Add support for SQS FIFO Queue

[jdinsel-xealth]

Story

To send a message to an AWS SQS FIFO queue, a message needs to have a MessageGroupId field. Without this, the sendMessage call will fail.

Changes

1. Added optional messageDeduplicationId and messageGroupId to the SendMessageRequestParameters interface
2. Added a _buildBody method that will add these values from the Request to the Form

Tests

This was tested locally with localstack using a FIFO queue. I added IDs to the SendMessageRequestParameters object passed to sendMessage and witnessed localstack accept the messages into the queue.
