Cloned from launchpad blueprint https://blueprints.launchpad.net/ceilometer/+spec/pipeline-configuration-cleanup.

Description:

Pipelines have are configured with the names of the counters they should produce, but they don't have a real list. Instead they have a set of wildcard patterns and negation options that can be used to test an individual counter by name. We should resolve that list fully when the pipeline is configured, so it is possible for the pipeline manager to ask the pipeline for a list of the counters supported by a pipeline. That will allow us to have the PublisherTask ask the pipeline which counters to collect, instead of having to work it out in advance.
