Node feature discovery for Kubernetes
This commits extends NFD master code to support adding node taints from NodeFeatureRule CR. We also introduce a new annotation for taints which helps to identify if the taint set on node is owned by NFD or not. When user deletes the taint entry from NodeFeatureRule CR, NFD will remove the taint from the node. But to avoid accidental deletion of taints not owned by the NFD, it needs to know the owner. Keeping track of NFD set taints in the annotation can be used during the filtering of the owner. Also enable-taints flag is added to allow users opt in/out for node tainting feature. The flag takes precedence over taints defined in NodeFeatureRule CR. In other words, if enbale-taints is set to false(disabled) and user still defines taints on the CR, NFD will ignore those taints and skip them from setting on the node.
