It would be nice to weave "Lifecycle pre and post deployment hooks" into the main section about training

I think we should probably add it to the existing wiring example, since we're already using it as a "catch-all" for several other things (deployment, rollback, etc).

Additionally, since we also are "requiring" people to fork the repo to do the rollback/activate examples they already have a fork that they can easily add the new table and hook-y stuff too.

I'll probably make an attempt to "do it live" during the training recording, and then go back and modify the material to better weave it in.
