Request for 'classic' confinement for flowbot

@ypcloud - AIUI, flowbot is a sort of orchestration tool and it seems that the orchestrating node could perhaps be strict, where it is receiving, sending and coordinating messages. Is that accurate?

What are typical workloads for the orchestrated nodes? You mentioned python, scrot, etc, but more precisely, what is run on these nodes? What privileges do they need to be run?

@pedronis, this appears to be a new use case, though it may resemble juju, which we allow classic.
