[aleksandarknezevic]

Describe the Feature

Add option to create IAM role which will be used for application version cleanup.

Expected Behavior

If user set option for creation IAM role, role should be created and lifecycle appversion_lifecycle will be configured in the same way as it is configured if user provided ARN of existing IAM role.

Use Case

User wants to enable appversion_lifecycle but doesn't want to create an IAM role in advance.

Describe Ideal Solution

Introduce a new boolean variable which will be false by default. If set, a new IAM role will be created and passed its Arn to appversion_lifecycle.

Alternatives Considered
