Markus Lehtonen 335b305d34 nfd-master: proper shutdown of nfd api informers 
Stop blocking on event channels when the api controller is stopped.
Ensures that the nfd API informer factory is properly shut down and all
resources released when stop() is called. This eliminates a memory leak
on re-configure events when leader election is enabled.

(cherry picked from commit 2bb8a72532)
