[Redeem][Application] sqsClient.sendMessageBatch should not exceed the batch size (current 10)

[binchoo]

As-is:
This code is trying to send the redemption requests for all users at once.
The batch size should be less than equal to 10.

PaimonGanyu/PaimonGanyu/application/src/main/java/org/binchoo/paimonganyu/lambda/redeem/RedeemCodeDeliveryLambda.java

Lines 62 to 70 in 429dea0

	private void sendToQueue(List<RedeemTask> redeemTasks) {
	List<SendMessageBatchRequestEntry> batchMessage = new LinkedList<>();
	for (int i = 0; i < redeemTasks.size(); i++) {
	batchMessage.add(new SendMessageBatchRequestEntry()
	.withId(String.valueOf(i))
	.withMessageBody(redeemTasks.get(i).getJson(objectMapper)));
	}
	sqsClient.sendMessageBatch(CODEREDEEM_QUEUE_NAME, batchMessage);
	}

To-be:
Split requests into groups whose size is less than or equal to 10.
