Hello!

Please add role based authentication functionality for AWS EC2 instance monitoring. For those who does not want to store credentials in macros.

Affected template:
https://www.zabbix.com/integrations/aws_ec2

Bit more details:
IAM roles for Amazon EC2 - Amazon Elastic Compute Cloud
Allow applications to make secure API requests by creating IAM roles and assigning them to your EC2 instances.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html

Retrieve security credentials from instance metadata

An application on the instance retrieves the security credentials provided by the role from the instance metadata item iam/security-credentials/role-name. The application is granted the permissions for the actions and resources that you've defined for the role through the security credentials associated with the role. These security credentials are temporary and we rotate them automatically. We make new credentials available at least five minutes before the expiration of the old credentials.

An instance of Zabbix server can automatically receive credentials in accordance with the role from which it is launched.
