instance_actions seems extremely useful, and at the ops meetups I've
been to has been one of the favorite features because it allows and easy
interface for "going back in time" to figure out what happened.
I'd suggest the following:
1. soft deleting and instance does nothing with instance actions.
2. archiving instance (soft delete -> actually deleted) also archives
off instance actions.
3. update instance_actions API so that you can get instance_actions for
deleted instances (which I think doesn't work today).
