Task without any containers
The RunTaskOperator does not require you to specify a container name only a
task definition name. As `boto3.run_task` is eventually consistent it does not
necessarily return the container name, depending on the task state. If we don't
set the name in the operator it is inferred from the api response (which could
be None due to eventual consistency) -> Thus we run the task with containers
but they are specified in the task definition, which is enough for the
RunTaskOperator. Hence my idea to infer them from the `describe_tasks` endpoint
if `run_task` returns no container.
