Hi ceilometer stackers, I've created the umbrella blueprints for central agent improvement https://blueprints.launchpad.net/ceilometer/+spec/central-agent-improvement. Please add the dependencies if I missed something. Besides, I'm appreciated if someone could comment on the spec of the bp https://blueprints.launchpad.net/ceilometer/+spec/support-resources-pipeline-item and to get it approved. -Lianhao
