[Feed] Wire suggestion consumption into user classifier.

The ActionApi implementation might not be the best place to get this
information from long term, it seems like the LoggingApi or the
SchedulerApi might be more logical places. However, only the ActionApi
currently knows when suggestions are used, so send them over for now.
