Remove the 'selinux' feature source and move the functionality under the 'kernel' feature source. The selinux feature label is changed to feature.node.kubernetes.io/selinux.enabled The selinux feature source was rather narrow in scope, and, the sole feature it advertised naturally falls under the kernel feature source.
