Description

Because we do not currently use a streaming response for nested container command health checks in the checker process, we are not able to display the output of failed checks (MESOS-7903), and we are not able to begin the health check timeout at the appropriate moment (MESOS-9944).

We should update the checker process to use a streaming response for the LAUNCH_NESTED_CONTAINER_SESSION call that it uses to initiate command health checks.
