Controller not found errors are logged in normal operation

[dwilding]

When using concierge prepare -p microk8s, I always see "ERROR controller concierge-microk8s not found". As I understand, this doesn't represent an actual error - it's an expected condition. Seeing an error is disconcerting. It feels like this would be better as an INFO message.

Sample output:

I see a similar error for the machine preset:
