Description

Right now, roles set up is (while asynchronous), is schedule / delay-based. In other words, there is a task that wakes up every so often and checks if the node is joined, and attempts to run auth setup. But with TCM, we can actually be certain about whether or not we are done with setup, and can deterministically run this task.This is a problem only for simulation (that said, does not cause any failures), but can still be a good general improvement.
