 * Test using various credential providers (see also https://docs.aws.amazon.com/sdk-for-java/v2/developer-guide/credentials.html):
 * - Elasticsearch Keystore (secure settings discovery.ec2.access_key and discovery.ec2.secret_key)
 * - Java system properties (aws.accessKeyId and aws.secretAccessKey)
 * - Environment variables (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY)
 * - ECS container credentials (loaded from ECS if the environment variable AWS_CONTAINER_CREDENTIALS_RELATIVE_URI is set)
 * - Instance profile credentials (delivered through the EC2 metadata service)
 *
 * Notably missing is a test for the default credential profiles file, which is located at ~/.aws/credentials and would at least require a
 * custom Java security policy to work.
