[ECS] [request] How to see the detail health check output if aws console shows `failed container health checks`

### Summary

I'm using aws ecs service, and once the service health check failed, I **ONLY see `failed container health checks` in the console, and no detail log found**

### Description

Aws console only shows `failed container health checks`, we need detail output. I found the [code](https://github.com/aws/amazon-ecs-agent/blob/89e9cb0/agent/api/container/container.go#L779) did have output field, could we find the detail output from the console, or by api?

### Expected Behavior
Could check the detail health check failed log, e.g. `curl 127.0.0.1:80 connection refused ...`, rather than an line of `failed container health checks`. Due to lack of information, people doesn't know how to fix that issue...

### Observed Behavior
Only show `failed container health checks` in aws console.

### Environment Details

### Supporting Log Snippets

Start with the linked agent/api/container/container.go location and compare its health-check output field with what the AWS console and API expose. The issue names no tests or implementation entry point beyond that file; completion would require establishing a supported way to retrieve and display detailed failure output instead of only the generic message.
