Shuangtai Tian d2dfb1b146 Handle the metrics sent by nova notifier 
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.
