> Currently, all Docker containers launched by {{DockerLinuxContainerRuntime}} get /sys/fs/cgroup
automatically mounted. Now that user supplied mounts (YARN-5534) are in, containers that require
this mount can request it (with a properly configured mount whitelist).
> I propose we remove the automatic mounting of /sys/fs/cgroup into Docker containers.
