Added startup and shutdown event notifications

@TimoGlastra this adds startup/shutdown notifications (as discussed on RocketChat I think?), let me know if this is what you were thinking. This is for the base wallet but assume we need something similar for sub-wallets?

This is great @ianco. Thanks for looking at this.

And also a lot simpler than I thought

I think this allows us to move several things out of the conductor startup (I'm thinking especially of mediator connection setup). We're working on some stuff related to queuing that would also benefit from this. Any chance we can go ahead and review the addition of these events and not wait until the author/endorser pieces are added? 🙂

For sure let's merge this and then I can do the rest of the work on a separate PR

LGTM!
