Expose FaultInjection status in TaskResponse

[xxx0624]

Summary

This change is to expose the FaultInjection status to the TaskResponse so that GetTaskMetadata in AgentState can facilitate shared Faults handlers to determine if the new endpoints should be exposed to tasks.

Implementation details

• Add a new field FaultInjectionEnabled to the https://github.com/aws/amazon-ecs-agent/blob/master/ecs-agent/tmds/handlers/v4/state/response.go#L32

Testing

Launch a task where the TMDS has this change and the new field is not visible in task metadata response

sh-5.2# curl ${ECS_CONTAINER_METADATA_URI_V4}/task | jq .
