[Openstack] [Ceilometer] Problem with nova resize events

Hi Jay and Julien

thanks very much for your help. I am not terribly familiar with github and code reviews, 
I am not a developer :(, so maybe I am not using the correct terms here.

We are using version 2013.1.2  of ceilometer, so we have no "ComputeInstanceNotificationBase" class in notifications.py, instead we have 

" class _Base(plugin.NotificationBase) ", which handles events with

        return ['compute.instance.create.end',

like ComputeInstanceNotificationBase does.

What is your suggestion in order to enable handlings of more compute events, considering we will go live in 2-3 weeks time?

1- We wait for Julien's patch to be approved and we upgrade to the patched version. 
2- We modify ourselves get_event_types() on our installation
3- ?

Not really a bug, but we know we could do better.
I've just cooked a patch that should improve that:
