Yeah, I think it's too ugly in ini format and would be better as a JSON
file so:
1. you don't have to rely on an amazing amount of external config files;
2. you don't have to see or edit it at all if you trust Ceilometer
   defaults.

Sorry, I should have re-read myself, this is not what I meant by
generic. I mean that they'll be indeed publisher specific, but that
every users will likely wants to use the same pipeline for the CW
publisher.

It's just that to me I would describe all pipelining in a configuration
file rather than mixing code and configuration.
