Set default_runtime_name to the runtime to be used

[shysank]

There was an issue in gpu operator where the nvidia-device-plugin pod was failing to start when containerd was used. On further inspection, we found that containerd 1.3 added a new property called default_runtime_name which sets the default runtime. Since this is not set when using gpu operator, it defaults to runc, and thus fails. This pr sets default_runtime_name to nvidia to use nvidia container runtime.
