[2.4] MAAS doesn't notice change in interfaces

[Andres Rodriguez]

Before, my interfaces were managed in e/n/i. Now my interfaces are managed in /etc/netplan/netplan.yaml. However, MAAS doesn't get interfaces from either place.

Instead MAAS scans for interfaces differently, and MAAS rack controller doesn't update the reality of the interfaces.

FWIW I did this:

1. restart regiond
2. restart rackd

And the interfaces were never updated.

I rebooted the machine, and interfaces *were* updated.

Can you please re-test this with Blake's fix to properly install the reactor? I think this was a symptom of "stalled reactor". When the service is properly running, we check the output of `ip addr` every 30 seconds and update the interfaces if there has been any change.
