> Due to the cgroups v1 implementation policy in linux kernel, we cannot update the value of
the device cgroups controller unless we have the root permission ([here|https://github.com/torvalds/linux/blob/6f0d349d922ba44e4348a17a78ea51b7135965b1/security/device_cgroup.c#L604]).
So we need to support this in container-executor for Java layer to invoke.
> This Jira will have three parts:
>  # native c-e module
>  # Java layer code to isolate devices for container (docker and non-docker)
>  # A sample Nvidia GPU plugin
