Type: Feature

Is your feature request related to a problem? Please describe.

Expose ECS (Fargate) metadata, similar to how EC2 metadata is currently exposed.

Describe the solution you'd like

Expose e.g. ECS task ARN as spring properties, so we can refer to it using @Value("ecs-metadata.task.TaskARN") or directly in application.yml: ${ecs-metadata.task.TaskARN}.

Describe alternatives you've considered

DIY lookup code, but this gets non-DRY fast, if used in many projects.
