Code review comment for lp:~cerberus/nova/nova_notifications

Looks great.

Not really a nit, just an observation:

It looks like the Notifier /class/ is superflous since we define a single stateless function inside of it and we don't derive the implementations from a base-class.

Should we just make each driver's `notify` proc a function which is called by `api.notify`?

As a side benefit, we get to avoid the cost of instantiating an object for each notification sent (of which there will be a gazillion), as well as the small penalty of later having to gc them.
