Publishers are configured into the pipeline to indicate where to push
samples data (e.g. to Gnocchi).
One of the publisher is notifier:// which sends the samples to the (now
deprecated) ceilometer-collector process.

Ceilometer collector stores data into other system via a dispatcher
mechanism (e.g. to Gnocchi). It's now deprecated as it's just, with
current architecture, a unnecessary step: publishers can do the job
directly.
