* this uses a serialized AWS signed request to the STS GetCallerIdentity
* endpoint.
* The logic is summarized as:
* 1. If imdsv2_session_token_url is provided in the credential source, then
* fetch the aws session token and include it in the headers of the
* metadata requests. This is a requirement for IDMSv2 but optional
* for IDMSv1.
* 2. Retrieve AWS region from availability-zone.
* 3a. Check AWS credentials in environment variables. If not found, get
* from security-credentials endpoint.
* 3b. Get AWS credentials from security-credentials endpoint. In order
* to retrieve this, the AWS role needs to be determined by calling
* security-credentials endpoint without any argument. Then the
* credentials can be retrieved via: security-credentials/role_name
* 4. Generate the signed request to AWS STS GetCallerIdentity action.
* 5. Inject x-goog-cloud-target-resource into header and serialize the
* signed request. This will be the subject-token to pass to GCP STS.
* @return A promise that resolves with the external subject token.
