Module lifecycle 

Deciding what lev daemon start / stop / status should do.

Each function here is the judgement part of a subcommand: given what was observed about the daemon, what has to happen and what gets printed. The observing is left to the caller, for the reason readiness::poll_until takes its predicate as an argument - the sequencing is worth testing, and only the probe needs a real socket or a real process.
