If you attempt to send a message to a FIFO queue with a request that contains the `DelaySeconds` parameter, the request fails with an `InvalidParameterValue` response.

This is actually a problem with ElasticMQ, but I'm creating an issue here to track that the version localstack is using gets updated if/when a fix is released.
