<p>
Unique, case-sensitive identifier you provide to ensure the idempotency of the request to create a deployment.
The service generates the clientToken when the API call is triggered. The token expires after one hour, so if you
retry the API within this timeframe with the same clientToken, you will get the same response. The service also
handles deleting the clientToken after it expires.
