The collector grew from doing one thing to doing too many. This encumber scalability and he's really a bad design as it is. Let's fix that. This patch take out the notification handling code to a new daemon called ceilometer-agent-notification. This daemon will be in charge of receiving notifications, storing them if needed, and building samples in from of it. Change-Id: I093f3b7855bd6ffff2018db9cd485ed2fc0f37a5 Blueprint: split-collector
