Nova compute node can now get metrics from monitors and send notifications to message bus. So, add listeners to handle the metrics in ceilometer. This patch changes the directory layout for compute notifications, because there will be other metrics (e.g. network and cache Qos) to be added. The deployer can also add the metrics they want. It's better to make a classification of these metrics. Nova blueprint utilization-aware-scheduling Change-Id: I6f54ef18035c437370360bbaff6d71666d0323fe
