A unique, case-sensitive identifier that you can provide to ensure that the request is idempotent. Idempotency
means that the request is successfully processed only once, even if you send the request multiple times. When a
request succeeds, and you specify the same client token for subsequent successful requests, the IoT Greengrass V2
service returns the successful response that it caches from the previous request. IoT Greengrass V2 caches
successful responses for idempotent requests for up to 8 hours.
