Integrating NFD Daemonset with KuD

Current NFD code in KuD is unused and obsolete.
Integrating NFD as DaemonSet and updating test case for NFD.
Added comments. Addressed comments and changed the
matchExpression to kernel features. Changed operator from "In" to Gt,
and values 4 to 3 better fit broader spectrum of O.S's.
Adding exit conditon in case there's an error status.
