ceilometer: add a polling section in ceilometer conf (SCRD-8720)

* Add a [polling] section to ceilometer.conf with cfg_file property which
  points to polling_pipeline.yaml

* removed default_domain_id and default_domain_name from  [service_credentials]
  and added project_domain_name and user_domain name to [service_credentials]
  in polling.conf to prevent ceilometer polling agent from failing with
  "need user domain" and "need project domain" error.

* added a new pipeline yaml file for polling agent, called polling_pipeline.yml

* added swift meters which are polling meters to polling_pipeline.yml
