Nvidia-docker: Support for CentOS 8

[DominikFilipiak]

1. Issue or feature description

CentOS 8 is not supported by nvidia-docker. It seems that it'll require podman as a default container engine, as with the issue #1040. Are there any plan to fix it soon, or should I downgrade the operating system?

2. Steps to reproduce the issue

[root@turing ~]# distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
[root@turing ~]# curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.repo | \
>   sudo tee /etc/yum.repos.d/nvidia-docker.repo
# Unsupported distribution!
# Check https://nvidia.github.io/nvidia-docker
[root@turing ~]# echo $distribution
centos8

I'll look into centos8 support sometime this month (pretty sure there's no difference).
In the meantime you can probably just set the distribution variable to centos7 that would allow you not to downgrade.

I did this sometime in the past week :)!
