Several questions about IMS context and different types of tokens. Want to make sure I understand how this is supposed to work.

A note: As this is backwards-incompatible, we cannot merge this PR until we're ready to do the auth cutover since it will block non-BIC changes from getting merged and released.

I am still concerned about token expiration, the library will just stop functioning once the token that's passed to init() expires and that's no good.

That's actually a good point. In many cases runtime actions are short lived, but for bulk operations they could run for far longer than 5 minutes. Please bring it up on the #commerce-project-app-builder-persistence channel. (I'll try as well, but I have other irons on the fire)
