Markus Lehtonen 0e1d4a9046 apis/nfd: migrate pkg/api/feature
Move the previously-protobuf-only internal "feature api" over to the
public "nfd api" package. This is in preparation for introducing a new
CRD API for communicating features.

This patch carries no functional changes. Just moving code around.
