Title:
update callback subscriptions of object methods to use decorator
Status in neutron:
Fix Released
Bug description:
We can now use @registry.receives("resource", ["event1", "event2"]) to
decorate methods in a class that should be subscribed to the callback
manager when its instances are created.
This improves readability for two purposes:
1. Using the decorator right above the method makes it easy to see when
looking at the code when the method is going to be called instead of having to
search for the component that subscribes it.
2. We can stop overriding __new__ in class definitions just for registry
subscriptions, which makes the class definitions a little cleaner.
See https://review.openstack.org/#/c/438489/ and
https://review.openstack.org/#/c/436353/ for examples.
