Defines and implements create|end|error notifications for all state-changing Trove API calls. Adds a notification to the TroveContext to transfer the notification to the guest and conductor so that errors on asynchronous commands can be forwarded to the Conductor to be transferred to the control plane bus. Also did some cleanup on the existing notifications to bring them all under a common framework in trove/common/notifications.py. The trove.instance.exists notification was not integrated into the new framework due to its close-coupling with the Nova notification code. Reworked the cluster action mechanism to move routing functionality from the strategy to the Cluster base class. This was done to support tying notifications to cluster specific actions. Implements Blueprint: ceilometer-integration Change-Id: I9c57d24f80d8d3116fc0cc8948094087a0495135
