Add support for fetching container identifier in ECS Fargate #2276
When an application is running inside of a Docker container, on a Linux guest, our agent is able to retrieve an identifier for that container via cgroups that are populated by Docker. However, when the host is AWS ECS Fargate, those cgroups are not present within the guest. Instead, a metadata API that is available to the guest should be consulted.
We should first attempt to look for the API endpoint through the URI available in the ECS_CONTAINER_METADATA_URI_V4 environment variable. If that environment variable does not exist, try the ECS_CONTAINER_METADATA_URI environment variable. If neither exist, exit with a failure as the function currently does.
