Issue MESOS-4670: `cgroup_info` not being exposed in state.json when ComposingContainerizer is used.
The ComposingContainerizer currently does not have a `status` method. This results in no `ContainerStatus` being updated in the agent, when uses `ComposingContainerizer` to launch containers. This would specifically happen when the agent is launched with `--containerizer=docker,mesos`
