Auto tag gpu node
This commit adds a new daemonset that tags the node with:
- node-role.kubernetes.io/gpu="true" if it detects a nvidia gpu device in the PCI lane.
To do this it uses the /sys/devices/pci000:00 bus information and the known NVIDIA device vendor code to search for one or more elegible cards.
