f58abdf966 Use scheduler cache in affinity priority functions 
Make the cache implement NodeLister and expose it to the priority
functions. This way, the priority functions make use of a single cache,
the scheduler's, instead of mixing it with the lister's caches.

1b447e8d19 Scheduler: Logging cleanup in predicates.go. 
This is some light cleanup of logs in predicates.go. In particular, some
log lines have details clarified that will make debugging easier.

I have not touched any VLOG messages, since those usually have plenty of
detail.
