add MessageAttributeNames to sqs.ReceiveMessageInput.

[yoanp]

I want to process by checking the attribute included in each message. Please review adding MessageAttributeNames to the worker.go Start method as shown below.

params := &sqs.ReceiveMessageInput{
    QueueUrl:            aws.String(worker.Config.QueueURL), // Required
    MaxNumberOfMessages: aws.Int64(worker.Config.MaxNumberOfMessage),
    AttributeNames: []*string{
        aws.String("All"), // Required
    },
    MessageAttributeNames: []*string{
        aws.String(sqs.QueueAttributeNameAll),
    },
    WaitTimeSeconds: aws.Int64(worker.Config.WaitTimeSecond),
}
