Support for initializers and instanceInitializers

[nicolaidahl]

First of all, thanks for making this possible! We're currently trying to use this repo as a migration path away from ember. That's why we're looking for something like this example but with support for initializers and instanceInitializers (of which we have around 10).

So far, we've tried extending the example with the ember-load-initializers npm package before realizing it was an ember addon.

Are you aware of any way to make initializers and instanceInitializers work with this setup?

Thanks
